The end-of-life (EOL) date for CentOS 7 passed on June 30, 2024, and with this milestone, businesses must evaluate their options for replacing this longstanding pillar of enterprise IT.
The termination of CentOS support means no more updates, patches or official assistance, posing significant risks to the security and operational stability of thousands of businesses. Continuing to run CentOS after EOL means serious financial risk, especially when hackers will deliberately target unprotected CentOS workloads. However, the forced transition away from CentOS can potentially be a large investment for organizations, as well.
This article details various options to deal with the CentOS end-of-life to minimize costs and maximize the return-on-investment. We’ll cover:
- The financial implications of the CentOS EOL
- Budget considerations for CentOS replacements, including migration and support options
- How to maximize cost savings with a zero-migration CentOS alternative
Although the CentOS EOL has financial consequences, this critical juncture offers an opportunity to transform your IT infrastructure, investing in a robust and reliable environment to foster growth for years to come.
The Financial Implications of CentOS EOL
Contents
With CentOS end-of-life, this means CentOS workloads will no longer receive security patches or updates, leaving your distributions vulnerable to cyberattacks. The average cost of a data breach globally was $4.45 million in 2023, according to the Data Breach Report 2023 by the Ponemon Institute. This staggering statistic illustrates the potential cost of each attack your CentOS distros will weather if they remain unprotected.
The cost of inaction underscores the urgency of making a decision for your CentOS workloads. You can choose to migrate to a new operating system or choose to continue running CentOS with added support. Let’s look more closely at the financial considerations for each of these options.
Budget Considerations for Migrating to a CentOS Replacement
When planning to migrate away from CentOS, it’s crucial to consider the financial impact. Here are key points to keep in mind when deciding whether to invest in a migration to a new operating system:
- Assessment Costs:
- Conduct a thorough inventory of all systems running CentOS.
- Identify dependencies and critical systems that require immediate attention.
- Resource Allocation:
- Determine the resources needed for the transition to the CentOS replacement, including hardware, software and personnel.
- Budget for new licenses, training staff on new systems and potential external support.
- Downtime and Migration Costs:
- Estimate the potential downtime required for transitioning systems to a new platform.
- Expect both planned and unplanned downtime, and schedule migrations to minimize disruption.
If you choose to migrate, be sure to research the performance and scalability of whichever new OS you’re considering. Read more about preparing your infrastructure for the CentOS EOL.
Potential Cost Savings with CentOS Support
Different models of continued support for CentOS can offer cost-effective alternatives to a full migration. These are the three main categories of support options for CentOS:
- Extended Support: Can offer updates, security, patches and technical support beyond EOL. It’s important to note that no first-party extended support is currently being offered for CentOS, and its current proprietors are advising a full migration to another Linux environment.
- Third-Party Support: Third-party vendors are offering support for CentOS, which includes patches, updates and technical support beyond EOL. Third-party support can often be more affordable and flexible compared to vendor-provided extended support.
- DIY (Do It Yourself) Support for CentOS: You can opt to create your own updates for your CentOS system after EOL. If you have deep Linux expertise on your team, this could be a viable option, but consider whether DIY is the most cost-effective or timely method of addressing vulnerabilities.
When considering external support for CentOS, consider the vendor’s history with Linux, their engineering staff’s expertise and the scope of support included in the contract. Dive deeper into your CentOS EOL support options.
Exploring CentOS Alternatives
When evaluating CentOS alternatives, several options are available, whether you plan to migrate or seek extended support. Each option has its own financial and operational implications:
- Free Linux Distributions:
- There are several free CentOS replacements to move to, but these require migration and adaptation to a new environment.
- Commercial Linux Distributions:
- Enterprise Linux solutions on other operating systems provide robust support for your workloads, but come with subscription costs; some still require complex migrations.
- Consider the total cost of ownership, including licensing, support and training.
- SUSE Liberty Linux:
- Continuity and Compatibility: SUSE Liberty Linux allows you to continue using your existing RPM-based setup, eliminating the need for extensive retraining or script rewrites.
- Cost-Effective Transition: With no migration required, you avoid the costs associated with building a new environment from scratch.
