DevOps can be a misunderstood term outside of tech circles. Is it a methodology? Is it an IT core competency? Or is it a cultural movement? By most accounts, it’s a sprinkling of all of the above – a bridge between development and operations.
When it comes to DevOps, there are three core principles: integration and communication, automation and repeatability, and big picture thinking. The mission of DevOps is to streamline and enable change, automation and repeatability. And like similar tech-leaning business initiatives (think Agile), as DevOps has become a critical component of innovation the enterprise has incorporated its ethos into many of its own tech operations. The migration to the cloud has speeded this adoption – making DevOps, the internet and some of the fundamentals of internet performance more important than ever.
What Enterprises Need to Know When Transitioning to the Cloud
Switching to the cloud brings both opportunities and risks for enterprise IT teams. Cloud deployment means relying on internet connections that are not always optimized for your organization (both internally, and for partners and customers). Moving from a traditional data-centric infrastructure to the cloud could potentially mean giving up control, as service providers are not focused on the connection between your users and your cloud/CDN assets. To add to the complexity, cloud and CDN connectivity performance can vary significantly by region, resulting in limited visibility and virtually eliminating performance control.
In deploying to the cloud, organizations need to shift their approach and embrace a comprehensive view of their apps and infrastructure, service platform and internet in order to control overall performance. Using the cloud requires more measurement than ever before. SysOps and CIOs have less control over the connections needed to monitor for security and performance considerations.
DevOps + Cloud Adoption = Perfect Combination
The combination of DevOps and cloud computing can be very beneficial for today’s enterprises because admins who are overseeing IT infrastructures likely have the same mindset, background and expectations for success. Organizations who are using a DevOps approach are seeing reliability, speed and quicker recovery from failure. DevOps is a journey through improved, quick and continuous software delivery – in many ways, the move to the cloud is embodiment of this approach and move to a performance platform that drives the agility of software execution. The two functions interlock to help your organization manage development and leverage performance, while eliminating environments that are prone to error.
So What Do DNS, DevOps and Internet Performance Have in Common?
DevOps enables enterprises to be agile, respond to performance issues, and more effectively move their data centers to the cloud. Having active monitoring and visibility of internet performance is key. Public internet variability can have a large impact on system-wide performance, so it is important to measure behavior from many points and ensure your DNS responses are optimized for your endpoints. A well run DNS platform directs users by service and location based on availability, performance and price variables. In a hybrid cloud environment, with multiple endpoints and public and private cloud assets, being able to direct users to the right resource is critical. DNS provides the steering direction to determine what is ‘right’ at any given time to modify your choice of destination.
The flexibility of the DNS provides a good basis for DevOps management of resources and allows you to be more flexible.
Plan for Success, Plan for Failure
Any CIO will plan assets to enable successful use cases, but ensuring configurations are planned to meet latency or security threats is just as important. If your organization plans ahead and has good alternatives in place, you can use DNS to direct traffic to the best, available choices. Here’s the good, the bad and the ugly when it comes to optimizing service performance:
- The Good: The Internet has many choices: path choices, destination choices, etc.
- The Bad: The internet is outside of your direct control and constantly changing. You need to maintain performance through constant monitoring and adjustments.
- The Ugly: Monitor and see issues and impacts as they happen; have contingencies in place to always stay up
