Like many other IT buzzwords, containerization has become a pervasive and common phrase—at least among enterprises that have embraced a DevOps mindset fueled by the forward-thinking development and operation teams. The fun doesn’t stop after you migrate your workloads to containers. There is life after containers—as early as the next day—or ‘Day 2’ as it’s commonly called.
Common container challenges
While containers have many far-reaching benefits to your digital transformation journey, the process does not come without challenges. IT evolutionary journeys like digital transformation warrant continuous dialog and improvements. While migrating appropriate workloads to containers can be challenging, there are additional challenges that arise post-migration, such as:
- Ongoing upgrades and maintenance of the environment
- Integrating existing technologies across the enterprise
- Monitoring, metering and management
- Container image scanning
- Proactive, timely remediation
- Compliance with regulatory and IT standards
So how can you overcome these obstacles?
Day 2 management
Once your workloads are successfully migrated and operational in containers, then comes the critical task of monitoring, maintaining and troubleshooting the operations to keep everything up and running—otherwise known as Day 2 management. A key driver for modernizing to containers is to move away from the high-cost maintenance of legacy platforms and simplify the IT environment. The resulting ‘technical debt’ from legacy investments can haunt IT leaders and hinder future planned processes. For companies and leaders who may already be losing sleep over piled-up technical debt, it’s even more imperative to make smart business decisions for future investments in next-generation technologies.
Consistency in the container platform—no matter the underlying environment—is key to streamlining Day 2 operations. This includes bare-metal and virtualized environments as well as various versions of private and public clouds. Automating Day 2 operations while maintaining transparency across these environments is another game-winning play you want to keep in your playbook.
The developer is the new consumer, at least internally. Empowering developers with the right levels of autonomy goes a long way toward advancing the DevOps mindset and culture of collaboration that fosters innovation. This consistency and collaboration create a toolkit of methods across the build, test and deploy cycle. Common challenges in the development stage involve the need to integrate the existing set of developer tools, as well as monitoring and metering the container resources. Integrated development environments (IDEs) with container workspace replicas that enable team collaboration with full access to source code is one way to address these challenges, especially when it is done without any of the code landing on hard-to-secure devices.
Why container security is a game-changer
Just because software is in a container doesn’t automatically ensure it is secure. Container content security needs to be continuously and proactively addressed. A three-pronged approach is commonly used to address this challenge:
- Control application security
- Defend the infrastructure
- Extend the security ecosystem
Hackers constantly collaborate to penetrate the technology solutions in place, and if they can collaborate, so should the enterprises that are embracing these technologies.
Open-source technologies that advocate an open platform with an open mindset are a great first step. It is no surprise then that data from the recent Red Hat State of Enterprise Open Source Report revealed 93% of financial services organizations believe open-source technologies are strategically and increasingly important for current and future plans.
