Have you ever encountered the situation where you need to expand your cloud infrastructure in order for certain workloads to be deployed, and once the demand is low, to cut back on your cloud spending? Most of us probably did, or at least know the many paths that need to be taken in order to achieve that.One of the team's responsibilities is to ensure that whenever a customer is about to deploy something, the burden of making sure that things are running and not costing unnecessary money is uplifted from them. These are just a couple of small pieces of a bigger puzzle. To get into a more detailed perspective, try to answer the following questions:

• What happens when the demand for resources decreases? What should we do?
• What kind of instance types to use (spot vs on-demand)?
• What to do when the cloud provider claims all of the spot instances back? Can we predict that?
• What is the most efficient way to handle all of the workloads while taking into account both cost and efficiency metrics?
• What is the visibility of all of the decisions that our engine is taking to both our customers and us?These are just several of the many questions that are part of the daily job when working in this team.Being part of this team would involve design and decision-making end-to-end while collaborating with colleagues from other teams. CAST AI, being a technical product, encourages not only to go and code something as written in the JIRA ticket but also to come up with new features and potential solutions to the problems that customers are facing.Here are some of the tools we use daily:
  • GoLang is our main language, while Python is an accepted alternative for some cases.
