Jinesh Varia, Technology Evangelist at Amazon.com created the following presentation to illustrate how Amazon EC2 instances are being used for creating high performance Web applications. He relies heavily on the integration technologies that unify the AWS Cloud Stack, which is shown to the right. To see a larger image of the stack, please click on it.
What is interesting about this slide deck is the detail it provides in explaining the more complex programming concepts of AWS. He provides useful insights into how Cloud Elasticity as an application platform component works through the use of detailed system-level diagrams. For example slides 21 and 22 are examples that show how Cloud Elasticity can be achieved with AWS Scaling Zones.
There are system-level definitions of AWS workflows including security that rely on EC2 instances as well. At 70 slides, this is an excellent overview of Web application development on AWS.
According to what Cisco is seeing in the market, the transition to private clouds starts with consolidation of systems and applications to reduce costs, followed by a targeted virtualization strategy.
Cisco sees this as a step to making their customers’ businesses more aligned to line-of-business strategies and goals. The final step is automation, which is the transformation of IT into a foundation for business strategies and future growth.
The following Cisco presentation has several interesting insights into how they are working with their clients to transition from data centers to private clouds. Results customers are achieving are provided throughout the slide deck, which provide a glimpse into the cost, time, and strategy savings from moving to private cloud architecture.
Cisco treads a fine line between showing a private cloud architecture that is entirely proprietary (like Oracle) and educating the market on how they see private clouds evolving. They do this by showing how commitment their product strategies are to open integration standards and how critical they see aligning to business strategies first. The net result is a useful 38-page presentation that is worth checking out, to see how they view the progression of data centers to private clouds occurring in the years to come.
