Get Started Today with Cloud-Ready Contracts | AWS Public Sector Summit 2017Amazon Web Services
In this session, we provide an overview of existing cloud-ready contracts, such as cooperative, federal, and state directed contracts, and walk through steps on how to choose the right one for your procurement. We compare various cloud-ready contracts by identifying scope, end-user eligibility, and primary service offerings to help you make the right choice for your mission needs. Learn More: https://aws.amazon.com/government-education/
In addition to the Cloud Maturity Model (CMM), the ODCA team have been working on a practical framework to guide implementation of the CMM, and to guide organisations with actions to achieve an increased cloud maturity level based on the increased business benefits that the increased levels should offer. This session will explore the capability areas, and a framework of actions (and resulting artefacts) leading between the various CMM levels.

Tenant-based resource allocation model for cost-effective scaling Software-as...Javier Mijail Espadas Pech
Computing resources are being transformed into a model consisting of services that are delivered in a similar way to traditional utilities such as water or electricity. One of the computing paradigms that have promised to deliver this utility computing vision is known as Cloud Computing. Cloud computing provides on-demand access to computational resources which together with pay-per-use business models, enables application providers seamlessly scaling their services. With cloud computing definition comes the term of elasticity which is the ability to create a variable number of virtual machine instances depending on the applications demands. Virtualization technology is widely adopted as an enabler of cloud computing because it provides benefits such as security, performance isolation, ease of management and flexibility of running within a user-customized environment. In the other hand, the cloud applications themselves have long been known to as Software as a Service (SaaS). SaaS is a software delivery paradigm where the software is hosted off-premises, developed by service providers and delivered via Internet and the payment mode follows a subscription model. For SaaS providers, having the power to scale up or down an application to only consume and pay for the resources that are required at certain point in time is an attractive capability and if done correctly it will be less expensive than running on traditional hosting. However, cost-effective scalability is not achieved just by deploying large-scale applications over pay-per-use cloud infrastructures, and idle processes and not used resources are wasted but charged to application providers. Over and under provisioning of cloud resources are still unsolved issues. Even if peak loads can be successfully predicted, without an effective elasticity model, costly resources are wasted during nonpeak times (underutilization) or revenues from potential customers are lost after experiencing poor service (saturation). In this sense, SaaS applications give an opportunity to improve this scenario due their multi-tenancy nature, which is the ability to offer one single application instance for several clients/providers (tenants). Each tenant can interact with the application as if it were an unique user and cannot access or view the data of another tenant. Consequently, with the use of cloud computing approaches such as on-demand virtual machine creation, it is possible to efficiently create a mechanism for SaaS applications in order to allocate, consume and charge only the required cloud computing resources by each tenant. This doctoral dissertation establishes formal measurements for under and over provisioning of virtualized resources in cloud infrastructures, specifically for SaaS platforms deployments and it proposes a resource allocation model to deploy SaaS applications over cloud computing platforms by taking into account their multi-tenancy thus creating a cost-effective scalable environment.

Nell'ambito del ciclo dei webinar CRUI, Commvault introduce il tema dell'adattamento delle strategie di data protection alle infrastrutture Cloud. Commvault tramite la propria piattaforma di Singular Information Management ha l’obiettivo di raggiungere un livello di protezione del dato il più elevato possibile. Abbinata alla piattaforma Microsoft Azure permette di trarre il massimo vantaggio possibile dal cloud e di garantire livelli di servizio convenienti, sicuri e flessibili. In un mercato in cui il cloud è il contesto di riferimento per la riduzione dei costi di capitale, l’uso della accoppiata Azure – Commvault permette di incrementare la velocità delle procedure, permettendo di risparmiare tempo e risorse.
La piattaforma Commvault è in grado di gestire semplicemente qualsiasi tipologia di ambiente composto da macchine fisiche, macchine virtuali, applicazioni,
desktop, laptop o cloud con la possibilità di accedere ai propri dati da semplici interfacce web o anche da applicazioni per smartphone e tablet.
Durante il seminario sono state illustrate le principali caratteristiche della piattaforma per valutarne la rilevanza per il Sistema dell’Istruzione e della Ricerca.

Why Cloud Computing?
• Cloud offers a variety of benefits including cost-saving, agility,
efficiency, resource consolidation, business opportunities and
green IT (Ambrust 2010, Foster et al, 2008; Kagermann et al.,
2011; Schubert, Jeffery and Neidecker-Lutz, 2010).
• Other characteristics include: Elasticity; Pay-per-use; Multi-
tenancy and so on.
• Armbrust et al. (2010) explain current challenges for cloud
computing which include (1) Vendors’ lock-in (2)
interoperability and (3) security. There are more researchers
focusing on technical rather than organizational/adoption
challenges. Identified adoption challenges:
1. “Best strategies and best practices for Cloud adoption”.
2. “No structured measurement of Cloud business performance”.
3. “Portability”.
4. “No connections between different services”.

Research Overview
• Not many frameworks address organizational challenges for Cloud
adoption. There are a few consulting firms offering similar but
expensive services.
• Cloud Computing Business Framework (CCBF) is the proposed future
work if I’m employed. CCBF has 4 key areas.
• Classification of business models to offer Cloud-adopting
organizations right strategies and business cases.
• Organizational Sustainability: Offer a structured framework to
review cloud business performance accurately.
• Portability: Deal with application portability from desktops to clouds
and, between clouds offered by different vendors.
• Linkage: Provide linkage between different cloud research
methodologies, and between IaaS, PaaS, SaaS and Business Models.
Business Integration as a Service (BIaaS) is used to demonstrate.
• It is a conceptual framework that can be validated in each
component and by simulations.

portability of all types, supported by
Financial Software as a Service (FSaaS)
and Healthcare Platform as a Service
(HPaaS).
No connections between
different services
How do you link and
integrate different
services?
Linkage: Link and integrate different
activities and between different types
of Cloud services. This develops a new
and innovative area called Business
Integration as a Service (BIaaS).

Portability
• Help organizations to migrate to Cloud – either building
from scratch or migrating from desktops to Cloud.
• Focus on Finance and Healthcare domains. Portability in
each domain can be different due to requirements etc.
• In Finance, Financial Software as a Service (FSaaS) is
used for demo, where Risk Assessment as a Service
(RAaS) is part of it. FSaaS uses Monte Carlo Methods
(MCM) and Black Scholes Model (BSM) for simulations.
• RAaaS has a series of steps of MCM (Variance-Gamma
Process, VPG; and Least Square Method, LSM) and BSM.
• Healthcare – focuses on Cloud Storage (won an award)
and 3D Bioinformatics.

Sequenc
e
Process What is aimed for Outcomes
1. (Variance Gamma
Process)
VGP in MCM
Detect and correct errors If errors are still found, run analysis
again. The improved analysis can be
passed onto next sequence.
2. Least Square
Method (LSM) in
MCM
Provide fast and reliable
calculations with an
excellent performance.
Obtain benchmark.
Most of calculations and benchmark can
be obtained here. If errors are found, go
back and check. The improved analysis
can be passed onto next sequence.
3. Risk Modeling in
BSM
To compute risk in 3D
Visualization. There are 3
different scenarios
presented.
The focus is to compute the extent and
risk, and present in a way to be visually
accessible. So that no hidden risk
involved. The improved analysis can be
passed onto next sequence.
4. Advanced risk
modeling
To obtain a good quality
of FSaaS on Cloud.
This can demonstrate the key benefits of
Cloud Portability: to allow speed,
accuracy, reliability, usability and
performance on using Cloud for FSaaS.

Linkage: presented by Business Integration as a Service (BIaaS)
Motivation:
• There is no communication between services. Each time two types of service
requests and activities have to done at different periods of time.
• Creation of additional work and cost. It also costs more to pay two service providers.
• It is difficult to check consistency of computational results from different service
providers.
BIaaS benefits (apart from cost-saving, improvements in efficiency etc):
• To allow two or more different services to work together where traditionally each
service would be separate from the others.
• To permit the outcome of one service to be used as input for another; integrating
two or more services into one.
Demonstration includes
• ROI Measurement as a Service (RMaaS): The aim is to measure Cloud business
performance. Work is similar to Organizational sustainability.
• Risk Analysis as a Service (RAaaS): The purpose of this service is to calculate risks
and evaluate its impact on an organisation. Work is similar to RAaS earlier (except no
3D risk).
Demonstration requires how RMaaS and RAaaS can work as a single service in a private
cloud environment.

In RMaaS:
• Statistical service: This computes Cloud business performance with key
statistical data offered by SAS, a statistical program.
• Visualization service: Results from statistical service pass onto this step
which presents key data using 3D Visualization enabled by Mathematica.
In RAaaS:
• VGP risk analysis service: This reduces inconsistencies and errors &
calculates the risk pricing, showing frequency of occurrence and risk pricing.
• LSM risk analysis service: This computes high-performing simulations and
calculates the most likely risk pricing and its upper and lower bounds.

Sustainability
Use CAPM to measure cloud business
performance and present complex statistical
data in 3D Visualization, which makes
analysis easier. This helps stake-holders to
understand their ROI of any Cloud projects.
OSM is presented in a way that CAPM has
never been used as before. It uses 3D
Visualization and is an improvement of a
Nobel-Prize model. 3D Visualization ensures
no hidden data or missing area for analysis. It is
easier to understand.
(Enterprise)
Portability
Demonstrate how portability can be achieved
including the use of HPaaS for platform
portability and FSaaS for application
portability. Experiments, simulations and
benchmarking are used to demonstrate
portability.
There are not many Cloud portability
demonstrations, although some are available in
industry and a very expensive service. CCBF
has developed HPaaS for GSTT and KCL, and
also FSaaS for IBM US, CBA and others.
Linkage Link and integrate different activities and
between different types of Cloud services. A
new concept, Business Integration as a
Service (BIaS), is used for demonstration
supported by case studies.
CCBF has provided services for University of
Southampton, Vodafone / Apple, University of

Conclusion
• Cloud Computing is highly relevant for IS and challenges are not
just technical.
• Cloud Computing (particularly private cloud) adoption is
important for organizations where Cloud deployment and design
need to match requirements and be able to overcome challenges.
• CCBF has 4 key areas and each area has its own contributions
supported by demonstrations and case studies. They are useful
for those organizations and enterprise research.
• CCBF is a dynamic framework that each case study meets the
different type of design, deployment and services.
