The Virtualization Practice

Agile Cloud Development

Agile Cloud Development focuses the aspects of agile development that integrate with cloud computing SaaS and PaaS environments including DevOps, Scrum, XP, and Kanban. ...
Major areas of focus include the Agile Development process and the pitfalls many companies encounter trying to implement it, the DevOps process and the pitfalls associated with its implementation. the organizational aspects of successfully implementing Agile Development and DevOps and the new tools that should be used to support Agile Development and DevOps processes. Covered toolsets include Agile Project Management, Continuous Integration, and Automated Deployment.

There is a new set of tools available for Caching up and down the stack which we covered within Caching through out the Stack, however in reality where is the best place to cache data for your application and what are the ramifications of using such a cache. Recently, we had a caching problem, actually two of them. Both caused by the same thing, a lack of full understanding about what was being cached. For any application, the best way to cache is to cache in memory as close to the application stack as possible, which in our stack could be within the application, the OS, or even a hypervisor based disk cache. However, which does your application actually use?

The Many Faces of PaaS

By now, enterprises understand the value of Software as a Service (SaaS) and Infrastructure as a Service (IaaS), but there still is much confusion about Platform as a Service (PaaS). This confusion is one reason why enterprises have been slow to adopt PaaS. Why is there so much confusion? Because PaaS is still in its early days of maturity, but it is growing up really quickly right before our eyes.

I just returned from attending the Cloud Expo in New York City this week. The conference was dominated by private and hybrid cloud topics. There were several private Platform as a Service (PaaS) vendors attending whom I spent a great deal of time talking to as I walked the floor. It seems these days that many enterprises default to private and hybrid clouds and therefore insist on private PaaS as well. It is critical that consumers of PaaS services understand the pros and cons of both public and private PaaS before making a commitment to a PaaS deployment model.

The Orchestration and Automation layer of the Software Defined Data Center is where the benefits of the SDDC is translated are translated into working applications for end users and business constituents. Every Cloud Management Platform relies upon either a script or one of these automation frameworks to provision and configure the actual end user services and applications. These solutions represent an opportunity to replace first generation automation management tools and scripts with modern declarative and model based approaches that are much more manageable and scalable.

I recently read the book Project Phoenix by Gene Kim, Kevin Behr, and George Spafford. If you are in development, IT, and Security it should be #1 on your reading list. In this book the authors discuss all the horrors we hear about in IT with a clear direction on how to fix them. There is politics, shadow IT, over zealous security professionals, over worked critical employees, lots of finger pointing. But there is a clear solution, at least as far as the story goes. We also know that DevOps works, most of the time.

Over the last few years there has been an increase in the number of database as a service (DBaaS) offerings that have entered the market place. IaaS providers like Amazon have released solutions such as RDS that automates database administration tasks in the area of scaling, replication, failover, backups, and more. There are a number of companies offering automation around NoSQL databases like Hadoop, MongoDB, Redis, Memcache, and numerous other database technologies.

The Cloud Management layer of the Software Defined Data Center is where the flexibility of the SDDC is translated into tangible benefits for the business constituents of the virtualized data center, the private clouds, the hybrid clouds and the public clouds. Without a robust Cloud Management layer, the IT Operations flexibility of the SDDC cannot translate into the relevant level of Business Agility for the business.
