System Design Interview - Distributed Cache

Topics mentioned in the video:
- Functional (put, get) and non-functional (high scalability, high availability, high performance) requirements.
- Least recently used (LRU) cache.
- Dedicated cache cluster, co-located cache
- MOD hashing, consistent hashing.
- Cache client.
- Static vs dynamic cache servers list configuration.
- Leader-follower (master-slave) data replication.
- Cache consistency, data expiration, local and remote cache, security, monitoring and logging.
- Memcached, Redis.

Inspired by the following interview questions:

[vigneshrajarajan]

this is the most underrated channel, kudos to your way of explaining things in succinct manner. Please put more videos

[mrunaldave]

Amazing content. So much to-the-point and valuable information packed in 34 minutes. This one video is equivalent to multiple hours of videos from other channels out there! Many thanks Mikhail.

I’ve been watching system design interview videos all over the place for the last 4 months. How come I’ve never seen this channel before?! Amazing quality and real technical depth!

[wildansyahidillah]

Wow, I think this channel has the best explanation of the available system design problems, which is able to provide a step-by-step explanation of how we get to the final design. Some other channels just slap the final design almost right away, which can be overwhelming and sometimes leave its sub systems inadequately explained.

Please add more system design problems, keep up the great work!

[Censik]

Got exactly this question on a system design interview. Thanks a lot! I was properly prepared. This is the best set of lectures on system design I've ever saw.

[YanruBi]

Discovering this channel in 2022, I wish there will be more updates. This is one of the best system design learning resources, and it's free. Every sentence is so on point. Thank you very much!

[fokkor]

Another great video, I can't say the importance of details in system design and as far as I've seen only your videos cover it. Don't get swayed by other 'scratching the surface' videos, keep up the good work!

[BitsnBytes]

The details and trade-offs you talk about clearly indicate that this information is acquired through a lot of practical experience. A lot of hard work has gone into this from your end. Thank you for sharing your knowledge. Look forward to more videos from your channel.

[pointtennis]

I like your style of repeating concepts throughout several videos. It helps reinforce them and allows the viewer several viewing opportunities to let it sink in over different videos (versus just watching the same video over and over to absorb something, which can get boring).

[manjunathks]

This is by far the best demonstration of designing a distributed cache. I really appreciate the way you brought up the the solution to a bigger problem in a progressive approach. Loved it. Keep growing.

[bloody]

The content that you've put is extremely high in quality, leaving nothing to chance. I haven't seen such pure content since DDIA. Many thanks for making it available for free.

[andrewsouthpaw]

This video provides an excellent balance of high-level concepts and diving deep into details. An incredible resource to find, and vastly better than many paid options out there on systems design.

[PankajSharma-cemj]

I'm short on words how good Mikhail explains things. Initially I was just going over the video without making any notes. Then once I started making notes, I realized there are tons of information in everything single component or design choice he explains.

[harzonline]

After watching many videos on consistent hashing, I am glad that I came across yours. The way you explained the process was simple and easy to understand. I really appreciate your efforts in putting together quality content.

[doruwyl]

Great explanation!
I hope you will continue with posting more System design interview videos. The fact that you started from the naive approach to a better solution I consider is a big thing to consider all pros/cons!

[RikiPoon]

The best system design demo i've even seen, with detailed and sound explanation behind each step in approaching the problems. Thanks!

[donaldbough]

Love the encouragement to dive into details. Easy to see how someone involving technical details instead of relying on managed services to handle it would make them stand out in an interview. Thanks!

[jasonmeyer]

I've watched all the popular channels on YT for system design and this one is without question the best one. Thank you so much for creating these videos. I hope you make more.

[MyQiman]

You know a video is good, when you have to pause the video constantly and process the information. Thank you so much for your time and effort on these high quality and thoughtful lectures!

[mrmca]

hands down, the best distributed cache explanation on Youtube. Every other video talks about caching and not distributed caching. This is a complete crash course on distributed caching.
