Symantec’s Avoiding the Hidden Costs of Cloud 2013 Survey found more than 90 percent of all organizations are at least discussing cloud, up from 75 percent a year ago. Other key survey findings showed enterprises and SMBs are experiencing escalating costs tied to rogue cloud use, complex backup and recovery, and inefficient cloud storage.
Skycon 2012 - Public, private, and hybrid; software, platform, and infrastructure. This talk will discuss the current state of the Platform-as-a-Service space, and why the keys to success lie in enabling developer productivity, and providing openness and choice.
Thanks to Tony Whitmore for the audio and to Patrick Chanezon for some pieces of the content.
The document is a summary of the 3rd Annual Survey 2013 on the Future of Cloud Computing conducted by North Bridge and GigaOM Research. Some key findings from the survey include:
- Hybrid cloud models are expected to become the norm with hybrid cloud usage projected to increase from 27% today to 43% in the next 5 years.
- Infrastructure as a Service (IaaS) saw the biggest growth of 29% from 2012, followed by Platform as a Service (PaaS) at 22% growth.
- Security remains the top barrier to cloud adoption but concerns are easing. Cost is now a growing concern compared to previous surveys where it was the top driver for adoption.
Intro to cloud computing — MegaCOMM 2013, JerusalemReuven Lerner
What is cloud computing? This is an introduction that I gave at MegaCOMM 2013, a conference for technical writers in Jerusalem. The talk describes how the combination of Internet access, virtualization, and open source have made computing a utility that we can turn on and off at will -- similar in some ways to electricity, water, and other utilities with which we're familiar.
Can we hack open source #cloud platforms to help reduce emissions?Tom Raftery
Cloud computing is changing our lives but this change comes with a cost - pollution.
Can we hack open source cloud platforms to make them report their energy and (more importantly) their emissions, so we can choose the cleanest cloud?

Building cross-region and cross could high availability into your app, a real life use case by Gigaspaces, Nati Shalom, Funder & CTO, Gigaspaces
Achieving high levels of availability and disaster recovery in a cloud environment requires the implementation of patterns and practices that introduce redundancy through multi-zone, multi-region, and multi-cloud deployments. As we move towards implementing higher availability, we cannot escape the direct increase in the accidental complexity of the deployment architecture resulting from lack of cloud portability and deployment lifecycle automation. We present how high availability and disaster recovery were achieved in reality by using the Cloudify open source framework on top of AWS. This approach applies to not just AWS but also other public clouds and private cloud environments such as Eucalyptus. The resulting reference architecture provides portable PostgreSQL replication and disaster recovery as well as application tier scalability across zones, regions, and public/private clouds through a unified deployment workflow.
LinuxFest NW 2013: Hitchhiker's Guide to Open Source Cloud ComputingMark Hinkle
Presented on April 27th, 2013 at LinuxFest NW
Imagine it’s eight o’clock on a Thursday morning and you awake to see a bulldozer out your window ready to plow over your data center. Normally you may wish to consult the Encyclopedia Galáctica to discern the best course of action but your copy is likely out of date. And while the Hitchhiker’s Guide to the Galaxy (HHGTTG) is a wholly remarkable book it doesn’t cover the nuances of cloud computing. That’s why you need the Hitchhiker’s Guide to Cloud Computing (HHGTCC) or at least to attend this talk understand the state of open source cloud computing. Specifically this talk will cover infrastructure-as-a-service, platform-as-a-service and developments in big data and how to more effectively take advantage of these technologies using open source software. Technologies that will be covered in this talk include Apache CloudStack, Chef, CloudFoundry, NoSQL, OpenStack, Puppet and many more.
Specific topics for discussion will include:
Infrastructure-as-a-Service - The Systems Cloud - Get a comparision of the open source cloud platforms including OpenStack, Apache CloudStack, Eucalyptus, OpenNebula
Platform-as-a-Service - The Developers Cloud - Find out what tools are availble to build portable auto-scaling applications including CloudFoundry, OpenShift, Stackato and more.
Data-as-a-Service - The Analytics Cloud - Want to figure out the who, what , where , when and why of big data ? You get an overview of open source NoSQL databases and technologies like MapReduce to help crunch massive data sets in the cloud.
Finally you'll get a overview of the tools that can help you really take advantage of the cloud? Want to auto-scale virtual machiens to serve millions of web pages or want to automate the configuration of cloud computing environments. You'll learn how to combine these tools to provide continous deployment systems that will help you earn DevOps cred in any data center.
[Finally, for those of you that are Douglas Adams fans please accept the deepest apologies for bad analogies to the HHGTTG.]
Delivering IaaS with Open Source SoftwareMark Hinkle
Mark Hinkle presented on delivering Infrastructure-as-a-Service (IaaS) using open source software. He discussed various open source tools for building cloud computing including hypervisors like KVM and Xen, object storage solutions like OpenStack Swift, and automation/orchestration tools like CloudStack and OpenStack. Hinkle emphasized that open source solutions provide many advantages for cloud computing including lower costs, collaboration, and avoidance of vendor lock-in. He also covered management tools for private clouds and highlighted the importance of automation.
Linthicum what is-the-true-future-of-cloud-computingDavid Linthicum
This document discusses the future of cloud computing. It begins with an overview of the history and growth of cloud computing. Emerging trends include more organizations adopting cloud services in practice rather than just discussing them, as well as greater focus on analyzing large amounts of data ("Big Data") in the cloud. The future of cloud computing is predicted to include it becoming a standard part of IT, improved security models, centralized data as a strategic asset, more powerful mobile devices, and integrated "composite clouds". The document recommends investing in platforms as a service, centralized identity management, service-oriented architectures, mobile applications, and companies that can aggregate various cloud offerings.
This document provides best practices for architecting applications in the cloud based on Amazon Web Services (AWS). It discusses 6 key practices: 1) Design for failure and nothing fails, 2) Build loosely coupled systems, 3) Implement elasticity, 4) Build security into every layer, 5) Think parallel, and 6) Leverage many storage options. Specific AWS services are recommended to implement each practice, such as using auto-scaling, SQS queues, and different storage services like S3, EBS, and RDS depending on data needs. The document aims to help architects take advantage of scalability, fault-tolerance, and other cloud attributes when building applications on AWS.
The Total Cost of Ownership (TCO) of Web Applications in the AWS Cloud - Jine...Amazon Web Services
Weighing the financial considerations of owning and operating a data center facility versus employing a cloud infrastructure requires detailed and careful analysis. In practice, it is not as simple as just measuring potential hardware expense alongside utility pricing for compute and storage resources. The Total Cost of Ownership (TCO) is often the financial metric used to estimate and compare direct and indirect costs of a product or a service. Given the large differences between the two models, it is challenging to perform accurate apples-to-apples cost comparisons between on-premises data centers and cloud infrastructure that is offered as a service. In this presentation, we explain the economic benefits of deploying a web application in the Amazon Web Services (AWS) cloud over deploying an equivalent web application hosted in an on-premises data center and highlight the 5 things to not forget while calculating TCO.

Explain the three established industry terms for cloud services
Speaker Notes:
There is a lot of talk in the industry about different terms like Platform as a Service, Infrastructure as a Service, and Software as a Service.
Since PDC08 when we first announced the Windows Azure our focus has been on delivering a platform as a service offering where you can build applications. Where the platform abstracts you from the complexities of building and running applications.
We fundamentally believe that the future path forward for development is by providing a platform. In fact, as you’ll see in a few minutes, we believe that there are a number of new capabilities that should be delivered as services to the platform.
Notes:
There is a lot of confusion in the industry when it comes to the cloud.
It’s important that you understand both what is happening in the industry and how we think about the cloud.
This is the most commonly used taxonomy for differentiating between types of cloud services.
The industry has defined three categories of services:
IaaS – a set of infrastructure level capabilities such as an operating system, network connectivity, etc. that are delivered as pay for use services and can be used to host applications.
PaaS – higher level sets of functionality that are delivered as consumable services for developers who are building applications. PaaS is about abstracting developers from the underlying infrastructure to enable applications to quickly be composed.
SaaS – applications that are delivered using a service delivery model where organizations can simply consume and use the application. Typically an organization would pay for the use of the application or the application could be monetized through ad revenue.
It is important to note that these 3 types of services may exist independently of one another or combined with one another.
