Cloud Engineer Interview Question: How to Whiteboard Elasticity vs Scalability!

[@samjones4327]

Hey what's up GPS!!! Thank u very much for this video! This is one of the best explanations of scalability and elasticity I've come across! Their definitions run so close together and you have visually clarified this for me! I appreciate it. I'm definitely gonna use this! And can u post it on your blog maybe? Be well, be safe and Peace!!!

Please yes more agnostic cloud content!!

[@crazyGodLikE]

This is interesting. In a way, aren't they one in the same? Elasticity is simply scaling more rigorously but both are essentially the same. What alternative is there to elasticity as a service and not a concept? With AWS, what would you substitute an ELB for, in terms of scalability? I may have misunderstood - just curious to know. Thanks

[@CarlaJenkinsTV]

Thanks for doing this video. Also if possible would you please do a video of the difference between high availability vs fault tolerance? Thanks.

[@evansimmonsofficial]

Scalability = Building up an existing resource (Like adding more RAM to a virtual PC). Elasticity = adding more resources to the pool to load balance (adding more availability zones, or virtual resources to handle workloads)... I think?

[@Lucas-iv6ld]

Great video, please post more interview questions, i'm getting prepared!

[@MadeByGPS]

More to come!

Elasticity's purpose is to match the resources allocated with the actual amount of resources required at any given point in time. Scalability, on the other hand, handles an application's changing needs within the constraints of the infrastructure by statically adding or removing resources to meet application demands as needed.

you asked chatgpt!!!!

[@UKIkarus]

Exactly right, and I'd even go so far as to saying that scaling is the more granular option as you can specify exactly what resources you want where to account for expected demand. Elasticity is dynamic and best used on a pay as you go subscription model where reducing the resources required alongside demand when there isn't very much going on can result in significant cost savings that would otherwise be spent on wasted capacity and increase when the metrics such as load on the systems meet a certain threshold automatically.

I had a vague idea of difference between the 2. The graphs did a great job explaining. Thank Gwyneth

[@marielosjauregui9065]

Gwyneth this is why you rock!

[@franciscomedinav]

This is very interesting. It can be confusing to understand both concept since they look like related to each other. Is auto scaling considered an elastic property??

[@MadeByGPS]

Autoscaling can be both, just depends on how you implement it.

So does it mean that elasticity comes with low latency? How fast it can scale the resources depending on the traffic?

[@gathe8290]

We'll put. Could you say elasticity is more granular?

Great explanation..much easier to grasp now

Excellent explanation, I can’t stress enough the importance of the learning and teaching the fundamentals, it makes digesting new technologies and tools more productive.

This is great! 🙌

[@ThoughtfulTechyCloud]

It would be great to also highlight the advantages that can be achieved in cost optimization with elasticity. Nice video!

[@MadeByGPS]

Could you expand more on that?

[@ThoughtfulTechyCloud]

@@MadeByGPS Sure! With elasticity you have the option to scale in which means your costs reduce when demand reduces.

[@immanuelt613]

I loved this video✨

[@nileyacob3126]

I am currently studying for my AWS Solutions Architect Associate exam and I came across these two concepts. They mean the same in Azure and GCP (I believe). Scalability would be using a more optimized version of the same resource. For example, if you have a spike in load, you will upgrade to a resource that has higher resources. The opposite if there is a drop in the load. Elasticity on the other hand is adding more of the services to handle the extra load and using something like a load balancer to spread the load between the resources. For instance, if you have a virtual machine (EC2 in AWS) and there is a spike in the load, you would put one or more EC2s online and a load balancer would distribute the load among them. Once the load has subsided, those newly added services can be taken down. This is elasticity.

you made this sound so simple. i wish people like you existed when i was in school, lol.
