Imagine having multiple services running, each has its own logs. Most people don’t read them, and they shouldn’t, because services emit a lot of logs! But we need them, because it’s the only way to diagnose and troubleshoot system errors. But you might say “my service is not a system! It’s only doing tiny stuff!” Gotta break it to you, your small part is a piece in a large system networks stitched together!...
Kubernetes is awesome, I think this is obvious if you have more than a handful of services to manage. If you use cloud, either VM or container-based runtime, it would provide you a dashboard to see the metrics. But what about kubernetes? Since you would have multiple services inside a single cluster, in which it’s backed by VMs, at best you would only see into your VMs’ metrics, but doesn’t provide separate metrics per each service....
Congratulations, you managed to successfully deployed a few services on kubernetes! But this is not the end 👀. Unfortunately money doesn’t grow on trees, and if you can’t justify your infra expenses, finance department won’t be happy. If you’re using Terraform, you can use Infracost to create a cost report. Pretty nifty. But what about kubernetes? Given cost reporting is a basic feature, kubernetes is no exception. Enters OpenCost, a vendor-neutral open source project for measuring and allocating infrastructure and container costs in real time....
Background Ever wonder how websites (and everything in between) work? Chances are you can create a project running on your local machine. It works as you expected, but to let other people access it, you have to “deploy” it. For many years, to support a lot of request volumes you need to run your applications in a data center. These days this setup is known as on-premise. Architecture Let’s take a look at a simple e-commerce website architecture....
Raise your hands if you normally have to send .env files to your team members so they can start a project in dev environment. While there is nothing wrong with this approach, it could introduce a lot of security risks, namely sharing secrets via plaintext protocol. Sure, you can share them on Slack, Discord, etc. But unless it’s encrypted with your own keys, it could be leaked if the said communication platform were to be breached....
