ExecutiveSummary
Over the last two decades, digitization has already brought about radical
economic and social change. But the trend is now gaining even more
momentum. Changing consumer behaviors and agile competitors with
new business models are putting enterprises under enormous pressure.
In the past, user departments would request the new functionality they
needed and gain approval from C-level executives, before the IT
department implemented it. But this lengthy procedure hampers agility
at a time of unprecedented market dynamism. Increased digitization
is putting IT at the very heart of company strategy, and demanding a
fresh, new approach, greater speed and improved flexibility. Against this
background, the in-house IT team must evolve from a reactive provider
to a proactive promoter and enabler of new, IT-driven business ideas.
This means today’s IT strategies must incorporate rapidly deployable
services. Enterprise IT will transform to become a supplier of IT services.
This approach will enable lines of business to try out and implement
innovations faster and more easily – without the need for their own
technical expertise.
Platform as a service (PaaS) includes a multitude of services delivered
from a cloud. Until now, it was regarded as a technical layer sandwiched
between infrastructure as a service (IaaS) and software as a service
(SaaS). However, PaaS is much more than a functional layer in a cloud
service architecture. It is the cornerstone of an entirely new, modular
ecosystem that delivers effective business support, and accelerates
time-to-market for new ideas.
Real-world examples underline just how business-
driven and efficient this kind of ecosystem can be –
providing a single platform for the operation and
modular delivery of solutions from multiple vendors.
PaaS opens up new business development opportunities to a wide range
of industries. Retail is a case in point. The internet has shaken up this
sector in terms of the type of players, sales channels, and logistics pro-
cesses. For example, retailers are now beginning to exploit customers’
smartphones as a way to sell their products. Innovative organizations see
these new trends as an opportunity to both strengthen existing customer
relationships and forge new ones. Couponing, motion analysis at the
point of sale, and proximity marketing are just some of the disruptive
applications coming into play. And these business tools are enabled by
the intelligent combination of complementary software.
Leveraging data captured by sensors is a further hot topic – creating
new possibilities by incorporating partners and customers in an eco-
system. There are billions of sensors around the world, and hundreds of
thousands of new ones are installed every day. Typically, they are deployed
to provide connectivity to cars and machines, and to manage data from
diagnostic systems in the field of medicine. Machine-to-machine solutions
measure, generate, share and process these vast quantities of sensor data.
But to allow the analyzed data to flow seamlessly into business processes,
M2M systems must be consolidated on a suitable platform and integrated
with existing systems landscapes and applications. And this is where
PaaS comes in, helping companies extract true business value from M2M
technology.
The PaaS ecosystem enables a new approach to IT, by paving the way for
better collaboration between the IT department, LOBs, senior executives,
software vendors and IT service providers. If it is deployed intelligently
and systematically, and operated efficiently, the modular PaaS platform
and ecosystem has the potential to become a key strategic business
management tool.

Cost pressure versus IT investments
IT generates fixed costs, which every CIO is under constant pressure to
cut. However, as digitization continues to change the world of business,
IT departments need to keep pace. This creates an apparent conflict.
Businesses are looking to deliver ever-greater responsiveness to cus-
tomers, partners and stakeholders, including real-time interaction; this
requires the development and deployment of innovative applications.
The budget tug-of-war between the IT and business departments can
only be resolved by the dynamic provisioning of IT resources, with pay-
per-use pricing. This creates a direct link between IT consumption and
business value added.
Users are now the decision makers
User departments not only regularly need new, improved, rapidly-provisi-
oned applications – they want to test their efficacy in advance. This has
led to a shift in decision-making power over IT investments, as confirmed
by research. In a 2013 IDC study, 56 percent of respondents stated that
they use cloud services without consulting their IT departments.1 A recent
survey by 2nd Watch suggests that 61 percent of LOBs that deploy cloud
services contact the provider directly, bypassing their IT organization.2
No matter whether an application is homegrown or provided by an
external vendor, business users are looking for specific functionality, and
want it implemented rapidly. Moreover, they want the new solutions
seamlessly integrated into the existing landscape, and with as little user
training and lock-in as possible.
Innovation is a business driver
The LOBs are looking for innovation – whether in logistics, customer
centricity, or sales strategies. They are under constant pressure to maintain
their competitive edge. And that calls for innovation that combines
efficiency with speed. Anything that goes to market too slowly is in danger
of being obsolete. There is therefore a need for self-service applications
that are available immediately. Industrialized IT factories are a proven
method for meeting this need. They provision the corresponding
services on demand, as standardized, scalable IaaS, PaaS and SaaS
offerings.
Platform as a service
PaaS was originally conceived as an industrialized cloud-based platform
service for application developers. Gartner’s definition highlights the
very technology-led character of PaaS. According to Gartner, in stack
diagrams PaaS offerings appear below the SaaS (software as a service)
layer and above the IaaS (infrastructure as a service) layer. PaaS offerings
comprise a wide range of application infrastructure (middleware)
services, including application platform, integration, business process
management and database services. The hype surrounding PaaS
primarily concerns application PaaS (aPaaS) as a representative of the
entire category. A PaaS is, in principle, a cloud service that includes both
development and production environments for application services.
Digitization is changing the face
of business IT

A high degree of usability and flexibility are central characteristics of
PaaS. The provider platform is accessed via application programming
interfaces (APIs); a local desktop, Internet connectivity, and a web browser
are required. Some offerings also assume the existence of a local
development environment. A provider is responsible for provisioning and
management of infrastructure, such as web servers, operating systems,
runtime environments, frameworks and middleware. Users enjoy highly
scalable infrastructure, computing power and storage capacity. What’s
more, the PaaS environment enables LOBs to run applications in SaaS
mode.
The PaaS market situation
Currently, PaaS is dominated by the major players. In Germany, PaaS
is available from T-Systems, Salesforce, Google, Amazon, IBM, Fujitsu,
Microsoft and others. According to Gartner, 33 percent of recent cloud-
computing investment in Germany has been in PaaS offerings that were
primarily leveraged by web developers to write or modify programs.
Google’s App Engine and the Salesforce and Microsoft platforms are
among the most widely-known PaaS products.
The growing potential of PaaS can be underlined by a number of
statistics: Salesforce has been on the market for only 15 years, but has
100,000 customers and generated revenues of over 3 billion dollars
in 2013. PaaS accounted for approximately 20 percent of this total.3
The Salesforce1 platform enables the rapid development of company-
specific apps for all devices, and for both customers and employees.
Salesforce’s AppExchange business app store is a full-fledged ecosystem
that offers pre-built, pre-integrated apps based around Salesforce for
practically any purpose.
IDC estimates total annual global revenue from PaaS offerings at approxi-
mately two billion dollars, and expects this to increase exponentially in
the next three years. The organization predicts that PaaS will generate
over 17 billion dollars in 2017.

PAAS – FROM TECHNOLOGY TOOL TO
FULL-FLEDGED BUSINESS SYSTEM
PAAS DEVELOPMENT TRENDS
PaaS was originally conceived as a tool to support SaaS and mobile and
social media applications. In terms of technology, its evolutionary journey
reflects its growing diversity and modularity. The PaaS scene now extends
to legacy applications, Java applications, frameworks, open interfaces,
and open-source software. All this has significantly broadened its scope,
with enhanced services creating a wealth of new possibilities for business.
Furthermore, PaaS offerings are now available for mobile solutions and
big data analytics. PaaS is increasingly being employed to support
mission-critical applications, such as CRM, BI and collaboration tools.
This makes it possible to perform analysis and generate reports based
on correlated data from all of these sources – anytime, anywhere.
User organizations benefit from the investments made by PaaS providers
and from economies of scale. They enjoy IT services on demand
delivered from a variety of cloud types. According to Gartner, 70 percent
of CIOs plan to deploy cloud services by 2016.4 IDC confirms that the
role of the IT department is changing from service provider to IT service
broker.5
The overall picture points to an emerging trend –
away from an ad-hoc approach to PaaS and towards
a more strategic one. At the same time, PaaS is
evolving from a developer platform into a rich and
diverse ecosystem.
COMPONENTS OF THE PAAS ECOSYSTEM
According to market analysts Ovum, the PaaS ecosystem consists of two
main areas, each with three components. It terms the two categories of
offerings “technology” and “ecosystem services”.

SERVICES
TECHNOLOGY SERVICES
The core technology component of PaaS are runtime services. These
consist of the application platform and its functionality plus operation
and administration. Runtime services are flanked on the one hand by IT
infrastructure, on the other by development services, related tools, and
developer-centric offerings.
ECOSYSTEM SERVICES
An ecosystem is a landscape consisting of the services offered by the
primary provider plus integrated partner services. Its purpose is not only
to offer business-enablement functionality such as payment processing,
but also to forge lasting ties between vendors and users by providing a
one-stop shop for developers. We believe that ecosystem services will,
in the long run, prove more important to the success of cloud (and PaaS)
service providers than technology services.6

APPAGILE FROM T-SYSTEMS
AppAgile is a PaaS offering that T-Systems has enhanced and extended
to create an efficient ecosystem. AppAgile not only meets the needs of
IT developers. It also addresses user departments’ need for the rapid
provisioning of new business functionality. At its core is the development
and operating platform that runs in the background, flexibly integrating
and coordinating all services.
A SINGLE, MODULAR, ALL-PURPOSE PLATFORM
The platform coordinates the execution of Java and database workloads,
offering what are known as containers for the development of custom
apps. This layer chiefly targets application developers, who were previously
compelled to build these systems themselves. User departments, by
contrast, are more interested in the speed of application deployment.
The layer above the infrastructure and the PaaS platform comprises
easy-to-implement, industry-specific application packages. Customers
can select from these according to the new software functionality they
require – and can combine them with home-grown and third-party
software. Connectors to in-house CRM and ERP systems enable data to
flow through the company’s IT landscape in all directions – a further key
factor for seamless integration.
THE TWO EDITIONS
Two versions of AppAgile are available: the Developer Edition and the
Production Edition. The editions’ individual modules can be combined
as required.
1. Developer Edition: A cost-effective version for development projects,
rapid application implementation, and simple migration of legacy
applications to T-Systems’ private cloud. Customers have full access
to the AppAgile DevOps platform. With this edition, support is only
available during office hours. It includes all license-fee-free middlewa-
re and services; licensed products are charged separately.
2. Production Edition: This full-fledged version offers comprehensive
support for business processes; T-Systems manages customers’
middleware instances 24x7. Customers can choose to manage the
applications themselves or transfer responsibility to T-Systems in the
form of dedicated projects. While they have no access to the platform
itself, they can view diverse reports.

A ONE-STOP PAAS PARTNER ECOSYSTEM
T-Systems has built an entire ecosystem for AppAgile – with an array of
software vendors already on board. This drives innovation, and helps
keep participants in lockstep with the latest developments and trends.
Customers choose the applications they need from the ready-to-go SaaS
solutions offered. These software packages can be linked, combined
and integrated, as can existing home-grown and third-party solutions
(ISV services). AppAgile brings together legacy and new software,
custom-developed and third-party functionality. With additional vendors
free to join at any time, the ecosystem is constantly growing, with
T-Systems as the service orchestrator. Organizations looking to deploy
multiple solutions benefit from industry-specific clusters of cloud-based
software, e.g. for retail and healthcare. These make it easy to identify
what solutions are available and combinable to meet an organization’s
specific application needs.
THE EIGHT MAIN BUSINESS BENEFITS
1. AppAgile is a full-fledged, ready-to-go ecosystem in the form of
a versatile, flexible integration platform. It enables rapid proof-of-
concept testing, and accelerates time-to-market.
2. The ecosystem brings greater speed, flexibility and scalability to
application development by providing a complete platform with self-
service functionality.
3. Customers can mix and match offerings from a range of software
partners without having to evaluate technical compatibility.
4. IT managers can quickly road-test a solution without investment
risk – and immediately commence enterprise-wide roll-out if it meets
their needs.
5. Significant savings can be made on investment, licenses and ope-
rating costs. Pay-per-use pricing includes SLAs and enables costs to
be accurately predicted in line with changing business demand.
6. The platform streamlines and simplifies interactions with customers,
partners and other stakeholders.
7. Big data solutions, e.g. for marketing, open up new possibilities
based on the identification and analysis of trends and opportunities.
8. T-Systems performs the role of service broker, orchestrating the
various offerings. At the same time, customers benefit from the
high security and availability standards fulfilled by T-Systems’ data
centers.

Retail
RETAIL – A FAST-EVOLVING SECTOR
New market entrants and limited consumer spending power are the main
competitive parameters in retail sector. The internet and smartphones
have brought about huge changes in consumer behaviors and had a
disruptive impact on the entire sector. Retailers are now limbering up
for digital battle. Some are developing new strategies for cross-channel
commerce or tightly integrated omnichannel sales – while at the same
time striving to retain the close customer relationships characteristic of
local small-town stores. Marketing, sales and after-sales communications
are becoming increasingly intertwined and reinforcing each other in a
bid to offer customers a new kind of shopping experience. Innovative
applications help identify and address new customer segments, build
loyalty, and attract prospective shoppers faster.

NEW APPLICATIONS SPELL NEW OPPORTUNITIES
How can retailers reach potential buyers via their smartphones? How
can a customer’s phone provide a retailer with valuable insight about
that person’s usage behavior and movements? Impulse buying at the
point of sale is a common phenomenon. According to McKinsey, bet-
ween 40 and 60 percent of purchasers can be influenced by promotions
at the POS.7 The retail sector has already invested heavily in an attempt
to discover why shoppers pick up a product, only to return it to the shelf
seconds later. Digitization is not only helpful in solving this mystery.
It also offers proactive methods for countering it – for example, by
sending a coupon to an undecided customer’s smartphone just the right
moment.
Gartner sees the customer experience – including
viral/social couponing – as the key field of invest-
ment for the retail sector in 2015.
A wide range of software solutions is now available for attracting shop-
pers and managing customer relationships. But in order to experiment
with these applications, LOBs generally have to invest in a great deal of
expensive technology, and the results often fall short of their expecta-
tions. What they need is a system that can be implemented rapidly and
combines a variety of individual solutions.
THE PAAS ECOSYSTEM FOR THE RETAIL SECTOR
Retailers can simply select the software they require from the large
range of products (SaaS offerings) available in the catalog. AppAgile
then combines these pre-built products to create an end-to-end solution
that can be integrated into existing system landscapes via connectors.
For example, a supermarket chain might choose a proximity marketing
solution complemented by a customer frequency analysis tool, plus a
couponing service that is activated just in time at the point of sale. All
these solutions are available from the platform in the form of standard,
ready-to-deploy modules.

11
In-house analysis by proximity marketing software enables the super-
market to directly address predefined target groups. For instance, a store
in a tourist location can immediately spot mobile devices with non-local
country codes. Sending a coupon for local specialties to these devices
encourages impulse buying. The solution can also register who is
standing in front of a shelf when, and in what position. A digital coupon
sent at precisely the right moment could encourage that person to pick
up a particular product. AppAgile even makes it possible to identify
coupons stored on a smartphone at the checkout, and apply discounts
automatically.
RAPID IMPLEMENTATION OF NEW BUSINESS IDEAS
In the past, launching new ideas brought uncertainty and high costs.
Now, businesses can pilot their innovations in a few selected stores
only – with no investment risk. And it is immediately apparent whether
the idea will be a hit or a miss. Test setups can be implemented quickly
and easily, and senior executives receive reliable facts and figures that
support rapid decision-making. This insight is extremely useful before
new marketing tools are rolled out across entire retail chains, someti-
mes spanning several countries. Moreover, these developments mean
in-house IT departments are not tied up by labor-intensive pilots and
application- development projects, but can concentrate on core tasks.

The Internet of Things is transformative
The term machine-to-machine (or M2M) denotes the automated exchange
of information by systems such as machines, vehicles or containers –
between themselves, or with a central point of control. Typical applications
include remote monitoring and control. M2M connects information
and communications technologies to form a network referred to as the
Internet of Things. Already today, there are more than 100 million M2M
connections worldwide – in the transportation, security, healthcare and
energy sectors.8 Growing network coverage, improved sensor perfor-
mance, and mobile access to cloud-based applications are propelling
this trend. New parameters such as smart metering and enhanced ana-
lytics with big data technologies are creating entirely new possibilities. A
remarkable 90 percent of all new passenger cars registered in 2024 will
be equipped with M2M technologies. In other words, there will be 700
million vehicles connected via the Internet by means of M2M solutions.9
The business benefits of M2M
How can M2M technology become part of end-to-end solutions –
comprising everything from transfer and analysis of machine data to
automatic control of equipment? How can solutions of this kind be
employed by large numbers of users via mobile devices? What new and
unanticipated service models will they enable, and what value-add could
they potentially create? How can existing modules be combined with
new ones to form a seamlessly functioning whole?
A manufacturer of industrial compressors provides a good example.
M2M sensors make it possible to measure the quantity of compressed
air generated by the equipment and consumed by the customer. The
combination of sensors and IT platform has given rise to a new pro-
duct – compressed air as a service – which customers can choose as
an alternative to buying the compressors. This offering enables the
manufacturer to evolve into a compressed air service provider. Service
of this kind can be extremely useful, for example, for projects where
huge quantities of compressed air are required for a limited period only.
Pricing can be based on the quantity of compressed air consumed, with
a service fee for equipment maintenance charged as an additional item
or included in the basic rate. Furthermore, the manufacturer can easily
carry out maintenance remotely using a predictive maintenance model
from T-Systems – a highly efficient option.

M2M WITH APPAGILE
AppAgile enables organizations to select the services they require to
set up and market new offerings from T-Systems’ SaaS portfolio. These
services are then combined in the PaaS ecosystem to create a made-to-
measure solution designed to fit the particular scenario. A major benefit
of this approach is that organizations can thoroughly test all aspects of a
solution and implement it fast. To stay with our compressed air example:
air-quantity data can be combined with power consumption and ambient
temperature readings, and analyzed. The findings can be presented
in various forms and made available to diverse groups of users, in line
with their respective access rights. This type of solution requires a
certain number of GSM modules and corresponding Deutsche Telekom
cell phone agreements. T-Systems is responsible for managing the
devices deployed. The GSM modules log onto the central platform via
an interface and store their log data there. From the central platform,
the data can be actively requested or forwarded at regular intervals. In
the near future, asset management, logistics and tracking will also be
implemented. This will allow the service provider to monitor the location
of its compressors at all times, and retrieve status information and error
messages from them. In critical scenarios, where rapid responses are
essential, the solution opens up a host of useful deployment opportunities.
AppAgile is a comprehensive, one-stop solution, providing all the under-
lying technology – from sensors to analytics.
AUTOMATIC IMPLEMENTATION OF NEW BUSINESS MODELS
The key advantage of AppAgile is speed. Its unique ecosystem means
projects and services that could previously only be launched with major
financial and time investments are now possible much faster. A second
benefit relates to innovation – offering new, pay-per-use services as an
alternative to buying equipment with a fixed price tag. Businesses not
only obtain a ready-to-implement model comprising a complete package
of one-stop services, but they also benefit from automatic process mo-
nitoring and optimization. This combination helps drive down costs by
improving efficiency and productivity. The possibility of fusing multiple
industry-specific clusters supports the creation of new business models
– which, in turn, help enterprises to broaden their customer base and
generate greater returns.
Healthcare
SHARING INFORMATION IN THE HEALTHCARE SECTOR
The introduction of the electronic health card in 1995 triggered a
digital revolution in Germany’s healthcare sector. What began with the
integration of health insurance companies with doctors and hospitals
has since assumed much greater proportions. The goal now is to involve
pharmaceuticals companies, pharmacies, physiotherapists, medical
equipment manufacturers and rehabilitation centers and most recently,
patients themselves, in the exchange of relevant information. The
underlying purpose is not only to improve efficiency but above all, to
create a common digital platform on which to build a viable healthcare
ecosystem.
Medical care is a complex, multi-faceted process involving a large number
of stakeholders and multiple elements – from diagnosis, treatment, and
patient data management, to administration and health insurance. For
various reasons, these sub-processes must be kept separate from one
another, but when integrated and digitized, they can deliver valuable
synergies for healthcare. Digitization can offer patients the convenience
of being automatically supplied with the correct medicine by their
pharmacies after a visit to the doctor. And it can enable health authorities
to automatically issue warnings should a regional epidemic arise.
Deutsche Telekom’s Healthcare Solutions unit supports the digitization
trend by establishing close ties with specialist healthcare providers and
by investing in promising start-ups.

13
MANAGING DIVERSE SERVICES
While hospitals do not generate income from software, the right IT appli-
cations can streamline their processes, helping cut costs. Data generated
at medical facilities can play a vital role in prevention, administration,
follow-up treatment, medical research, education, and official statistics.
How can this information be shared appropriately while preventing it
from getting into the wrong hands? How can a billing system integrated
with an insurance company handle services provided by multiple parties?
And how can a software vendor create a solution for care facilities that
ensures that every resident always receives the correct medication?
APPAGILE JOINS THE DOTS
The healthcare sector is served by many specialist companies that
create software for very specific purposes. As a result, user organizations
gain mature modules that facilitate or streamline one or more of their
business processes. Healthcare companies or software providers can
choose the components they wish to deploy from a catalog of healthcare
solutions offered as SaaS.
AppAgile combines these individual products to form an end-to-end
solution that can be integrated into an existing systems landscape by
means of connectors. The core purpose of the solution is to increase the
efficiency of the treatment process through the use of digital functiona-
lity. More efficient treatment means faster recovery and in turn, lower
costs. This not only benefits the health insurance companies who bear
those costs, but the entire economy.
For example, combining software for patient records and document
exchange can give rise to new functionality for managing bed occupancy.
And anonymized patient records can lead to the creation of new tools
in the fields of diagnosis, allergy therapy and medication. In the past,
combining automatic, sensor-based monitoring of intensive-care and
long-term care patients with alarm systems and analytics software was
a huge and expensive undertaking. With AppAgile, this type of solution
becomes a standard, low-cost, patient-centric tool.
The potential applications are many and varied, and offer scope for
creating innovative products and services that improve the standard
of care delivered to individuals, and the healthcare system as a whole.
Since the majority of data in this sector is of an extremely sensitive
nature, security and data protection are of utmost importance. The core
technology at the heart of T-Systems AppAgile has been certified to
German DIN ISO 13485 criteria for sensitive patient records. The benefit
to healthcare providers, users and solution developers alike is that this
eliminates the need to certify individual modules.
SECURE INTEGRATION, FIRST-RATE SUPPORT
The secure, digital integration of all healthcare participants not only helps
patients receive the best possible treatment. It also reduces unnecessary
administration work for all parties, leads to more effective prevention,
and drives down costs. From prevention to aftercare, for hospitals and
outpatients, the entire healthcare delivery chain is transformed into a
single, tightly integrated whole.

14
A NEW RELATIONSHIP BETWEEN LOBS AND IT
In the broad sense of an ecosystem, PaaS offers a host of new pos-
sibilities to all involved – be they users, software developers, hosting
providers or vendors. Companies can open up new opportunities for
their lines of business to sharpen their competitive edge without putting
undue strain on the IT budget. New applications in the form of service
packages require minimum development effort and can be made availa-
ble immediately. They can initially be implemented on a small scale for
testing purposes and then quickly scaled up if they prove successful.
This in turn lays the foundations for a new corporate culture of coopera-
tion within the organization: LOBs will no longer regard IT as a restrictive
element, but as a tool that enables them to explore new freedoms and
put ideas into practice fast. Time-to-market shrinks, giving the business
the edge over competitors. Each company must decide for itself whether
PaaS or the AppAgile ecosystem should be integrated with backend
systems or employed as a stand-alone solution.
APPAGILE OFFERS FAR MORE THAN PAAS
In technical terms, AppAgile is an integrated system that combines
hardware and software, managed operations and applications to create
a new, strategic tool for corporate management. Against this background,
deciding to utilize AppAgile does not simply mean opting for a particular
kind of information technology. It is a strategic corporate decision. And
the value-added that AppAgile delivers can impact business success.
Radically accelerated application development can be the difference
between a market-leading and me-too product. And being able to test-run
a solution on a small scale minimizes the risk of poor investments when
it comes to large-scale innovation projects.
THREE REAL-WORLD SCENARIOS
Major corporations can leverage AppAgile to establish a dedicated
department for business development – for example in the form of a stra-
tegic staff unit. The unit can develop and test new product ideas, sales
strategies or business models at little effort and expense, and present
them fully fledged to senior executives for approval.
Conclusions
LOBs can use AppAgile as a tool for testing new products. It enables
start-ups to launch their business on a small scale without significant
fixed costs – to introduce both new products targeting very specific
market segments and those sold directly. Users can leverage the full
functionality of all available modules without concerning themselves with
the underlying technical infrastructure, as this is provided and managed
by T-Systems. Via a self-service portal, start-ups can market the new
applications as their own products. Thanks to AppAgile’s full scalability,
they can precisely align capacity, and therefore cost, with the growth of
the business. This means they can meet the demand of their investors for
predictable costs and rapid success in the marketplace.
SUCCESS OF A MODULAR ARCHITECTURE
AppAgile is based on a modular, construction-kit principle with T-Systems
providing building blocks of every conceivable kind. Enterprises and
software developers select the blocks they need to to create their target
applications. T-Systems then assembles these to form end-to-end
solutions, which it operates on its tried and trusted platform.
AppAgile is available in two versions, differing in the scope of support.
This dual approach has proved very useful: the Developer Edition
enables developers, to a large degree, to manage the technical platform
and, in particular, the middleware, themselves. The Production Edition,
on the other hand, is a fully managed and full-featured service package
for supporting business processes, with the option of tasking T-Systems
not only with managing the middleware but also with running the
applications. AppAgile’s already broad range of deployment scenarios
is expanding all the time with new building blocks continuously being
added to the platform and ecosystem. All businesses – from start-ups
to established companies looking to deliver new and improved services
– are under the same pressure to innovate and drive down costs. The
AppAgile ecosystem provides an answer for everyone, delivering an
integrated, future-driven business platform for the operation of rapidly
deployable software modules.
