What is the Sidecar pattern and why is it heavily used in micro-services

Sidecar Pattern is an architecture where two or more processes living in the same host can communicate with each other via the loopback (localhost) essentially enabling interprocess communication. It is the foundation architecture on which service meshes such ad LinkerD and Envoy is built on.

In this video, we will explain, how we do things the classical way and how the sidecar pattern works, the pros and cons. Sidecar pattern also enabled the service mesh such as linkerd and istio that make microservices even better.

While sidecar pattern popularized in the containerized environment you can use it in the non-containerized environment as well.

Pros
* Decoupling thick libraries and references,.
* Applications can evolve independently.
* Polyglot - Each sidecar application can be written in its own language

Cons
* Latency
* Complexity

Stay Awesome!

Nice trade-off between decoupling (isolation) and operationally coupling concerns. It should be great if you also discuss circuit breaker and fallback (Chain of Responsibility) as you already mentioned the possibility of a service not being available in the last minute. Overall great presentation!

So in nutshell, It's an Internal Microservice Architecture ;-)

perfect. just what I needed to "externalize" some directories in one container to use in another. thanks!

[RuslanSkiraUkraine]

Hard to understand but I very much appreciate your videos.

[eddylin]

Wow. What a fantastic explanation and love the energy. Really helpful for learning as a beginner :D

Might be it's too late now but one question coming up in my mind, how it is then different from having a specialized service exposed via API or JMS? Because that service would also be accessible via API or topic/queue

If you're developing this type of application use a Unix socket if you can. The programming interface is almost identical, but it's considerably faster.

Hussein, first of thank you thank you thank you, secondly can u do a video on actual logging best practices? When you should log, what should be logged, and implementation? If like to know what industry standards are, what's too much, what s not enough...

[anasouardini]

why not use pipes instead of that? the only thing will slow you down is the context switching

[shivarajbakale]

Hey man, I've been following your videos and they're excellent. Can you please make a crash course on Kubernetes?

[richardwang]

man, you guess it. I am searching sidecar containers and I find this, nice video,

[tarekali]

Thank you so much for making these great videos

[anmoldeep]

@hussein - make a video on Java BigInteger internals - covering the basic constructor BigInteger(string, radix);

[ShivamSharma-xzje]

In Istio we have Envoy as side car pattern

[romantsyupryk]

Thanks so much for this video tutorial.

Just realized this guy sounds like the Shelby's Shawarma guy 🤣

[alirezabahrami]

why your talking like that it took some minutes for me to get it when you say communication "communukashan" :')

[yesh]

You have excellent content on your channel. Maybe its just me, but I am used to such instructional videos having a "standard" voice and I tend to find your modulations distracting me from getting any benefit from these videos

[dasabhishek]

It would be better, if you can just explain on the subject without so much humor. Its distracting.
