Doug’s Answer

I agree with Brandon's answers given that new engineers out of school that wish to work on services that run in the cloud will be trained on the job. That said, I can give you some additional context on what it is like. The primary difference between cloud services and programs that run on devices like Android phones is the sheer volume of requests that is made to the code that provides a service (such as Google search, YouTube, Instagram, Facebook, etc.). In order to handle large volumes of requests, the code is distributed across many computers so that each computer is handling some of the requests. When the number of requests increase, the number of computers are also increased in order to handle the load. So, the skills that engineers have to develop to build and maintain services in the cloud include the following:

1) Build high quality modular code that incorporates logging

2) Ability to write services that can scale out by adding/removing more machines when needed

3) Ability to rapidly troubleshoot issues with services by reading logs

4) Ability to add good metrics to service code so that it can be monitored for issues (such as the number of requests/second that the service is handling)

5) Ability to write code that can be shipped incrementally and continuously

So, in addition to learning how to code and work with algorithms and data structures, the above is also needed. Many many tools are being developed to make the above easier, so becoming familiar with tools and what they do helps (such as Docker, Kubernetes, Grafana, ...). Finally, larger companies such as Google, Facebook, Amazon, and Microsoft have their own infrastructures that engineers have to learn. That said, becoming familiar with concepts such as micro services, monitoring, logging, scaling out, deployment, devops, continuous integration, and continuous delivery will give you a leg up. Here are some articles to get you started.

Pooja’s Answer

"1. Understand basic cloud terminologies :
- High availabilty, Scalibility, Agility, Disaster Recovery, etc related to cloud computing
- Difference between IaaS, PaaS, SaaS
- Difference between Public Cloud, Private Cloud, Hybrid Cloud

2. Virtualization :
Provisioning virtual machines, understanding of virtualization and serverless computing lessens hardware dependencies and improves scalibility

3. API and Web Services :
Web services and API help us to integrate web applications on internet. XML,SOAP are some open standars used to tag and transfer data.
Example : For Microsoft Azure, we can use REST APIs to start batch jobs where we can send multiple operations in single request and get the
result in single response.

4. Containers: Containers are packaging mechanisms that can decouple cloud applications from their target environment.
Such application are easier to deploy. Example - Kubernetes, Docker

5. Storage : Here it means that large amount of data is stored online in cloud. It is easier to manage and access such data than in normal filesystem.
It is necessary to understand what data is to be stored where and which type of storage in cloud.
Example : In AWS - S3, Glacier. Microsoft Azure - Storage tables, Azure SQL (Relational Database), Blob storage. Data stored in cloud
has high availabilty and can be restored easily.

6. Networking : Good understanding of networking and virtual networks is required because data has to be accessed over them. Cloud engineers provide efficient
system so that fewer customer devices are needed to manage the system.

7. Programming skills : Programming skills required in creating, deploying and managing applications in cloud. Java, Javascript, Python are some languages/
scripts used in cloud computing. C#/.Net framework, PowerShell Scripts especially for Microsoft Azure.

We can take subscription of any of such Cloud Service Providers (AWS/ Azure) to get hands-on with them and refer links below for certificate preparation:

AWS certified Cloud Practictioner : https://aws.amazon.com/certification/certified-cloud-practitioner/
AWS certified Developer : https://aws.amazon.com/certification/certified-developer-associate/
Azure (AZ-900) Fundamentals : https://docs.microsoft.com/en-us/learn/certifications/exams/az-900
Azure (AZ-203) Developer Asscociate : https://docs.microsoft.com/en-us/learn/certifications/exams/az-203"

Brandon’s Answer

To become a cloud engineer it is going to be necessary to familiarize yourself with the core concepts of software development, the tools that you have available to you from the various cloud providers, and some understanding of the business that you work for in order to understand why your lead decided on a particular infrastructure to tackle a problem.


Brandon recommends the following next steps:

Do well in your software development classes and side projects. Making sure to write modular code that you could deploy.
Familiarize yourself with Docker, Docker is a way to deploy a consistent environment with your projects. https://www.docker.com/resources
Familiarize yourself with cloud service providers. This may be a bias but start with AWS since they are very prevalent in industry and have a rich collection of services. https://www.aws.training/Details/Curriculum?id=27076&scr=path-cp
