CEP and SOA: An Open Event-Driven Architecture for Risk Management, March 14, 2007, IIT Financial Services 2007, Lisbon, Portugal, Tim Bass, CISSP, Principal Global Architect, Director Emerging Technologies Group
Cloud computing comes into focus only when you think about what IT always needs: a way to increase capacity or add capabilities on the fly without investing in new infrastructure, training new personnel, or licensing new software. Cloud computing encompasses any subscription-based or pay-per-use service that, in real time over the Internet, extends IT's existing capabilities.
Cloud architecture, conception and computing PPTNangVictorin
These platforms hide the complexity and details of the underlying infrastructure from users and applications by providing very simple graphical interface or API (Applications Programming Interface). Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.
GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

Key Trends Shaping the Future of Infrastructure.pdfCheryl Hung
Keynote at DIGIT West Expo, Glasgow on 29 May 2024.
Cheryl Hung, ochery.com
Sr Director, Infrastructure Ecosystem, Arm.
The key trends across hardware, cloud and open-source; exploring how these areas are likely to mature and develop over the short and long-term, and then considering how organisations can position themselves to adapt and thrive.
3. What is Cloud Computing?
• Cloud Computing is a general term used to describe a new class of
network based computing that takes place over the Internet,
– basically a step on from Utility Computing
– a collection/group of integrated and networked hardware, software
and Internet infrastructure (called a platform).
– Using the Internet for communication and transport provides
hardware, software and networking services to clients
• These platforms hide the complexity and details of the underlying
infrastructure from users and applications by providing very simple
graphical interface or API (Applications Programming Interface).
3
4. What is Cloud Computing?
• In addition, the platform provides on demand services, that are always on,
anywhere, anytime and any place.
• Pay for use and as needed, elastic
– scale up and down in capacity and functionalities
• The hardware and software services are available to
– general public, enterprises, corporations and businesses markets
4
5. Cloud Summary
• Cloud computing is an umbrella term used to refer to Internet based
development and services
• A number of characteristics define cloud data, applications services and
infrastructure:
– Remotely hosted: Services or data are hosted on remote
infrastructure.
– Ubiquitous: Services or data are available from anywhere.
– Commodified: The result is a utility computing model similar to
traditional that of traditional utilities, like gas and electricity - you pay
for what you would want!

13. Basic Cloud Characteristics
• The “no-need-to-know” in terms of the underlying details of
infrastructure, applications interface with the infrastructure via the APIs.
• The “flexibility and elasticity” allows these systems to scale up and down
at will
– utilising the resources of all kinds
• CPU, storage, server capacity, load balancing, and databases
• The “pay as much as used and needed” type of utility computing and the
“always on!, anywhere and any place” type of network-based computing.
13
14. Basic Cloud Characteristics
• Cloud are transparent to users and applications, they can be built in
multiple ways
– branded products, proprietary open source, hardware or software, or
just off-the-shelf PCs.
• In general, they are built on clusters of PC servers and off-the-shelf
components plus Open Source software combined with in-house
applications and/or system software.
14
15. Software as a Service (SaaS)
• SaaS is a model of software deployment where an application is hosted as
a service provided to customers across the Internet.
• Saas alleviates the burden of software maintenance/support
– but users relinquish control over software versions and requirements.
• Terms that are used in this sphere include
– Platform as a Service (PaaS) and
– Infrastructure as a Service (IaaS)
15
16. Virtualization
• Virtual workspaces:
– An abstraction of an execution environment that can be made dynamically
available to authorized clients by using well-defined protocols,
– Resource quota (e.g. CPU, memory share),
– Software configuration (e.g. O/S, provided services).
• Implement on Virtual Machines (VMs):
– Abstraction of a physical host machine,
– Hypervisor intercepts and emulates instructions from VMs, and allows
management of VMs,
– VMWare, Xen, etc.
• Provide infrastructure API:
– Plug-ins to hardware/support structures Hardware
OS
App App App
Hypervisor

Virtualized Stack
17. Virtual Machines
• VM technology allows multiple virtual machines to run on a
single physical machine.

etc.
18. What is the purpose and benefits?
• Cloud computing enables companies and applications, which are system
infrastructure dependent, to be infrastructure-less.
• By using the Cloud infrastructure on “pay as used and on demand”, all of
us can save in capital and operational investment!
• Clients can:
– Put their data on the platform instead of on their own desktop PCs
and/or on their own servers.
– They can put their applications on the cloud and use the servers
within the cloud to do processing and data manipulations etc.
19
19. Cloud-Sourcing
• Why is it becoming a Big Deal:
– Using high-scale/low-cost providers,
– Any time/place access via web browser,
– Rapid scalability; incremental cost and load sharing,
– Can forget need to focus on local IT.
• Concerns:
– Performance, reliability, and SLAs,
– Control of data, and service parameters,
– Interaction between Cloud providers,
– No standard API – mix of SOAP and REST!
– Privacy, security, compliance, trust…
20
22. Cloud Storage
• Several large Web companies are now exploiting the fact that they have
data storage capacity that can be hired out to others.
– allows data stored remotely to be temporarily cached on desktop
computers, mobile phones or other Internet-linked devices.
• Amazon’s Elastic Compute Cloud (EC2) and Simple Storage Solution (S3)
are well known examples
– Mechanical Turk
23
23. Amazon Simple Storage Service (S3)
• Unlimited Storage.
• Pay for what you use:
– $0.20 per GByte of data transferred,
– $0.15 per GByte-Month for storage used,
– Second Life Update:
• 1TBytes, 40,000 downloads in 24 hours - $200,
24
24. Utility Computing – EC2
• Amazon Elastic Compute Cloud (EC2):
– Elastic, marshal 1 to 100+ PCs via WS,
– Machine Specs…,
– Fairly cheap!
• Powered by Xen – a Virtual Machine:
– Different from Vmware and VPC as uses “para-virtualization” where
the guest OS is modified to use special hyper-calls:
– Hardware contributions by Intel (VT-x/Vanderpool) and AMD (AMD-
V).
– Supports “Live Migration” of a virtual machine between hosts.
• Linux, Windows, OpenSolaris
• Management Console/AP
25
25. EC2 – The Basics
• Load your image onto S3 and register it.
• Boot your image from the Web Service.
• Open up required ports for your image.
• Connect to your image through SSH.
• Execute you application…
26
26. Opportunities and Challenges
• The use of the cloud provides a number of opportunities:
– It enables services to be used without any understanding of their
infrastructure.
– Cloud computing works using economies of scale:
• It potentially lowers the outlay expense for start up companies, as
they would no longer need to buy their own software or servers.
• Cost would be by on-demand pricing.
• Vendors and Service providers claim costs by establishing an
ongoing revenue stream.
– Data and services are stored remotely but accessible from
“anywhere”.
27
27. Opportunities and Challenges
• In parallel there has been backlash against cloud computing:
– Use of cloud computing means dependence on others and that could possibly
limit flexibility and innovation:
• The others are likely become the bigger Internet companies like Google
and IBM, who may monopolise the market.
• Some argue that this use of supercomputers is a return to the time of
mainframe computing that the PC was a reaction against.
– Security could prove to be a big issue:
• It is still unclear how safe out-sourced data is and when using these
services ownership of data is not always clear.
– There are also issues relating to policy and access:
• If your data is stored abroad whose policy do you adhere to?
• What happens if the remote server goes down?
28
28. Advantages of Cloud Computing
• Lower computer costs:
– You do not need a high-powered and high-priced computer to run cloud
computing's web-based applications.
– Since applications run in the cloud, not on the desktop PC, your desktop
PC does not need the processing power or hard disk space demanded by
traditional desktop software.
– When you are using web-based applications, your PC can be less
expensive, with a smaller hard disk, less memory, more efficient
processor...
– In fact, your PC in this scenario does not even need a CD or DVD drive, as
no software programs have to be loaded and no document files need to
be saved.
29
29. Advantages of Cloud Computing
• Improved performance:
– With few large programs hogging your computer's memory, you will
see better performance from your PC.
– Computers in a cloud computing system boot and run faster because
they have fewer programs and processes loaded into memory…
• Reduced software costs:
– Instead of purchasing expensive software applications, you can get
most of what you need for free-ish!
• most cloud computing applications today, such as the Google
Docs suite.
– better than paying for similar commercial software
30
30. Advantages of Cloud Computing
• Instant software updates:
– Another advantage to cloud computing is that you are no longer faced
with choosing between obsolete software and high upgrade costs.
– When the application is web-based, updates happen automatically
• available the next time you log into the cloud.
– When you access a web-based application, you get the latest version
• without needing to pay for or download an upgrade.
• Improved document format compatibility.
– You do not have to worry about the documents you create on your
machine being compatible with other users' applications
31
31. Advantages of Cloud Computing
• Unlimited storage capacity:
– Cloud computing offers virtually limitless storage.
– Your computer's current 1 Tbyte hard drive is small compared to the
hundreds of Pbytes available in the cloud.
• Increased data reliability:
– Unlike desktop computing, in which if a hard disk crashes and destroy
all your valuable data, a computer crashing in the cloud should not
affect the storage of your data.
• if your personal computer crashes, all your data is still out there in
the cloud, still accessible
– In a world where few individual desktop PC users back up their data
on a regular basis, cloud computing is a data-safe computing platform!
32
32. Advantages of Cloud Computing
• Universal document access:
– That is not a problem with cloud computing, because you do not take
your documents with you.
– Instead, they stay in the cloud, and you can access them whenever you
have a computer and an Internet connection
– Documents are instantly available from wherever you are
• Latest version availability:
– When you edit a document at home, that edited version is what you
see when you access the document at work.
– The cloud always hosts the latest version of your documents
• as long as you are connected, you are not in danger of having an
outdated version
33
33. Advantages of Cloud Computing
• Easier group collaboration:
– Sharing documents leads directly to better collaboration.
– Many users do this as it is an important advantages of cloud computing
• multiple users can collaborate easily on documents and projects
• Device independence.
– You are no longer tethered to a single computer or network.
– Changes to computers, applications and documents follow you through
the cloud.
– Move to a portable device, and your applications and documents are
still available.
34
34. Disadvantages of Cloud Computing
• Requires a constant Internet connection:
– Cloud computing is impossible if you cannot connect to the Internet.
– Since you use the Internet to connect to both your applications and
documents, if you do not have an Internet connection you cannot
access anything, even your own documents.
– A dead Internet connection means no work and in areas where
Internet connections are few or inherently unreliable, this could be a
deal-breaker.
35
35. Disadvantages of Cloud Computing
• Does not work well with low-speed connections:
– Similarly, a low-speed Internet connection, such as that found with dial-up
services, makes cloud computing painful at best and often impossible.
– Web-based applications require a lot of bandwidth to download, as do large
documents.
• Features might be limited:
– This situation is bound to change, but today many web-based applications
simply are not as full-featured as their desktop-based applications.
• For example, you can do a lot more with Microsoft PowerPoint than with
Google Presentation's web-based offering
36
36. Disadvantages of Cloud Computing
• Can be slow:
– Even with a fast connection, web-based applications can sometimes
be slower than accessing a similar software program on your desktop
PC.
– Everything about the program, from the interface to the current
document, has to be sent back and forth from your computer to the
computers in the cloud.
– If the cloud servers happen to be backed up at that moment, or if the
Internet is having a slow day, you would not get the instantaneous
access you might expect from desktop applications.
37
37. Disadvantages of Cloud Computing
• Stored data might not be secure:
– With cloud computing, all your data is stored on the cloud.
• The questions is How secure is the cloud?
– Can unauthorised users gain access to your confidential data?
• Stored data can be lost:
– Theoretically, data stored in the cloud is safe, replicated across multiple
machines.
– But on the off chance that your data goes missing, you have no physical
or local backup.
• Put simply, relying on the cloud puts you at risk if the cloud lets you
down.
38
38. Disadvantages of Cloud Computing
• HPC Systems:
– Not clear that you can run compute-intensive HPC applications that use
MPI/OpenMP!
– Scheduling is important with this type of application
• as you want all the VM to be co-located to minimize communication latency!
• General Concerns:
– Each cloud systems uses different protocols and different APIs
• may not be possible to run applications between cloud based systems
– Amazon has created its own DB system (not SQL 92), and workflow system (many
popular workflow systems out there)
• so your normal applications will have to be adapted to execute on these
platforms.
39
39. The Future
• Many of the activities loosely grouped together under cloud computing
have already been happening and centralised computing activity is not a
new phenomena
• Grid Computing was the last research-led centralised approach
• However there are concerns that the mainstream adoption of cloud
computing could cause many problems for users
• Many new open source systems appearing that you can install and run on
your local cluster
– should be able to run a variety of applications on these systems

Editor's Notes
Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.
cloud computing customers do not own the physical infrastructure.
Cloud computing users avoid capital expenditure (CapEx) on hardware, software, and services when they pay a provider only for what they use.
Low shared infrastructure and costs, low management overhead, and immediate access to a broad range of applications
ScalabilityInfrastructure capacity allows for traffic spikes and minimizes delays.
ResiliencyCloud providers have mirrored solutions to minimize downtime in the event of a disaster. This type of resiliency can give businesses the sustainability they need during unanticipated events.
Homogeneity: No matter which cloud provider and architecture an organization uses, an open cloud will make it easy for them to work with other groups, even if those other groups choose different providers and architectures.
On-demand self-service. A consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with each service’s provider.
Broad network access. Capabilities are available over the network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, laptops, and PDAs).
Resource pooling. Multi-tenant model.. There is a sense of location independence in that the customer generally has no control or knowledge over the exact location of the provided resources but may be able to specify location at a higher level of abstraction (e.g., country, state, or datacenter). Examples of resources include storage, processing, memory, network bandwidth, and virtual machines.
