When to use 𝐊𝐮𝐛𝐞𝐫𝐧𝐞𝐭𝐞𝐬 and when not to!

A Very common question from fellow DevOps Engineers when they start their Kubernetes journey: “When to use Kubernetes and When not to use Kubernetes!”, let me give you very straight-forward answers via important points:

🚀 𝐖𝐡𝐞𝐧 𝐭𝐨 𝐔𝐬𝐞 𝐊𝐮𝐛𝐞𝐫𝐧𝐞𝐭𝐞𝐬:

📈 𝐒𝐜𝐚𝐥𝐚𝐛𝐢𝐥𝐢𝐭𝐲:

When you have applications that need to scale dynamically based on demand.

🧩 𝐌𝐢𝐜𝐫𝐨𝐬𝐞𝐫𝐯𝐢𝐜𝐞𝐬:

If you’re adopting a microservices architecture, Kubernetes can manage and orchestrate your containers efficiently.

🛡️𝐑𝐞𝐬𝐢𝐥𝐢𝐞𝐧𝐜𝐞:

For applications that require high availability and self-healing capabilities.

☁️🌍 𝐌𝐮𝐥𝐭𝐢-𝐜𝐥𝐨𝐮𝐝 & 𝐇𝐲𝐛𝐫𝐢𝐝 𝐂𝐥𝐨𝐮𝐝:

If you’re looking to avoid vendor lock-in and want to run your workloads across multiple cloud providers or in a hybrid environment.

🔄 𝐂𝐈/𝐂𝐃 𝐈𝐧𝐭𝐞𝐠𝐫𝐚𝐭𝐢𝐨𝐧:

Seamless integration with CI/CD tools for automated deployments.

❌ 𝐖𝐡𝐞𝐧 𝐍𝐨𝐭 𝐭𝐨 𝐔𝐬𝐞 𝐊𝐮𝐛𝐞𝐫𝐧𝐞𝐭𝐞𝐬:

🎯 𝐒𝐢𝐦𝐩𝐥𝐞 𝐀𝐩𝐩𝐥𝐢𝐜𝐚𝐭𝐢𝐨𝐧𝐬:

For small-scale applications with minimal architecture, Kubernetes might be an overkill.

📚 𝐋𝐞𝐚𝐫𝐧𝐢𝐧𝐠 𝐂𝐮𝐫𝐯𝐞:

If your team doesn’t have the bandwidth to learn and manage Kubernetes, it might be challenging initially.

💰 𝐂𝐨𝐬𝐭:

Setting up and running a Kubernetes cluster might not be cost-effective for small projects.

🏛️ 𝐋𝐞𝐠𝐚𝐜𝐲 𝐀𝐩𝐩𝐥𝐢𝐜𝐚𝐭𝐢𝐨𝐧𝐬:

Some older applications might not be suited for containerization or might require significant refactoring.

⚙️ 𝐈𝐧𝐟𝐫𝐚𝐬𝐭𝐫𝐮𝐜𝐭𝐮𝐫𝐞 𝐎𝐯𝐞𝐫𝐡𝐞𝐚𝐝:

Kubernetes introduces an overhead in terms of resources. Ensure you’re ready for that commitment.

NOTE: While Kubernetes is powerful, it’s not a silver bullet. Evaluate your project needs and decide accordingly. 🤔💡
