This is the fifth and final in a series of posts that delves deeper into the questions that IDC’s Mary Johnston Turner and Gary Chen considered in a recent IDC Analyst Connection. The fifth question asked:
What types of technologies are available to facilitate the integration of multiple generations of infrastructure and applications as hybrid cloud-native and conventional architectures evolve?
Mary and Gary write that “We expect that as these next-generation environments evolve, conventional and cloud-native infrastructure and development platforms will extend support for each other. As an example, OpenStack was built as a next-generation cloud-native solution, but it is now adding support for some enterprise features.”
This is the one aspect of integration. Today, it’s useful to draw a distinction between conventional and cloud-native infrastructures in part because they often use different technologies and those technologies are changing at different rates. However, as projects/products that are important for many enterprise cloud-native deployments–such as OpenStack–mature, they’re starting to adopt features associated with enterprise virtualization and enterprise management.

This is the fourth in a series of posts that delves deeper into the questions that IDC’s Mary Johnston Turner and Gary Chen considered in a recent IDC Analyst Connection. The fourth question asked:
What about existing conventional applications and infrastructure? Is it worth the time and effort to continue to modernize and upgrade conventional systems?
In an earlier post in this series, I discussed how both the economics and disruption associated with the wholesale replacement of existing IT systems makes it infeasible under most circumstances. In their answer to this question, Mary and Gary highlight the need for these existing systems to work together with new applications. As they put it: “Much of the success of cloud-native applications will depend on how well conventional systems can integrate with modern applications and support the integration and performance requirements of cloud-native developers.”

This is the third in a series of posts that delves deeper into the questions that IDC’s Mary Johnston Turner and Gary Chen considered in a recent IDC Analyst Connection. The third question asked:
How will IT management skills, tools, and processes need to change [with the introduction of cloud-native architectures]?
Mary and Gary note that the move to hybrid architectures “switches the IT operations team’s priorities from maintaining specific components to ensuring the delivery of end-to-end services measured in terms of service-level agreements (SLAs).” They also note that there’s a huge cultural element. For example, “Line-of-business stakeholders will have to partner with IT operations and development staff, either individually or as part of collaborative DevOps groups, to ensure that services are implemented as expected and that test-and-release cycles are well integrated.
