Autoscaling is the process of dynamically allocating

the resources required by an application to match

performance requirements and satisfy service-level

agreements (SLAs), while minimizing runtime costs

Horizontal Scaling:

Vertical Scaling:

Vertical (often referred to as scaling

up and down). It is all about

modification of Computing power

based on requirement of expansion or

reduction of its capacity and

performance.

Example : Adding RAM on each VM

based on requirement

Horizontal (often referred to as scaling out and

in). It is all about deploying the solution on

additional or fewer resources based on

requirement.

Multicloud Autoscaling

Now if we say autoscaling for Multi-cloud it is the same, but involves using different

cloud provider.

Theoretically it is a easy solution – the way you manage autoscaling for single

provider you need to manage the same way for multiple providers but practically it is

way more complex when implemented in real environment.

Usecase and Challenges in

managing MultiCloud Autoscaling

One of the leading multinational company that designs and manufactures athletic and casual

footwear and clothing planned to run a marketing Sales offer campaign for a period of 10 days.

Their complete infrastructure is with one of the leading public cloud service provider based in

UK.They have their DR running in another public cloud based in APAC region which means that

their complete infrastructure is in Multicloud environment.

Now with marketing campaign they see 20x increase in users.

Offcourse it is a overwhelming news for Marketing Sales or CEO of the company but at the same

time it is a matter of concern for Ops manager if the infrastructure will be abble to handle this

sudden spike.

It is even more challenging for ops manager to manage that demand spike when they have a

multicloud environment.
