Top skills: what employers want in a cloud engineer
Whether you’re new to the cloud or can expertly pilot your way through, you may already know which skills to hone in on for a career in cloud computing. But we’re serving up something extra—the top skills employers are looking for in candidates (based on Indeed data).
1. Amazon Web Services (AWS)
Though the battle of AWS vs. Azure continues, Indeed job postings show that AWS tops the list as the highest in-demand skill for cloud engineer roles.
The first major cloud provider on the market, AWS is now a leader in infrastructure as a service, but also notably strong in platform as a service. In fact, AWS grew a staggering 47% in 2018 and accounted for most of its parent company’s profit, holding 41.5% of application workloads, whereas Azure sits at 29.4%.
With the widest range of offerings spanning compute, storage, networking and database, AWS is Linux-friendly and offers integrations for open source apps. You’re likely to come across AWS whether you’re looking to work at a startup or enterprise because of its affordable pricing model with more flex and a mature environment for big data.
And although it’s not uncommon for companies to take a multi-cloud approach, AWS is, more often than not, the first cloud provider adopted by companies before entertaining thoughts of expansion.
Steadily rising in popularity over the years, Stack Overflow’s developer survey shows that Python is the second-most-loved programming language of 2019.
With Python’s versatility and flexibility, it’s no surprise it ranks as the second most in-demand skill for cloud engineers. Not just a winning solution to make sense of data, especially in artificial intelligence and machine learning, Python is also a top choice when it comes to creating and deploying scalable apps that take complete advantage of the cloud’s offerings.
Other benefits to knowing Python as a cloud engineer—aside from being a resume booster—include helping you work with cloud-specific tools written in Python, like AWS SDK for Python and OpenStack’s official clients.
Linux is powering a whopping 90% of the public cloud workload as of 2017. Because Linux is the third most sought-after skill in cloud engineers, familiarity with the operating system will likely give you a head start on your competition.
Fortunately, even if you haven’t made the jump to cloud engineering yet, the same Linux skills used on-premise are transferable to the cloud computing world—and just as useful.
Fighting repetitiveness with automation, shell scripting earns a top spot on the list of in-demand cloud engineering skills. After all, it’s hard for businesses to say no to higher productivity at a fraction of the effort.
Linux shell is a good start, seeing as about 50% of Azure virtual machines are Linux, according to Scott Guthrie, Microsoft’s executive vice president of the cloud and enterprise group. Writing scripts in Python is another way to automate tedious tasks in the cloud. You can even use scripting tools provided by AWS to manage cloud resources, like pausing and starting EC2 instances, putting backups on autopilot and administering servers remotely.
5. Microsoft Azure
Although behind AWS in terms of demand, Azure is still a major player in the cloud computing world—and that’s in light of its late entry as a cloud services provider, four years behind AWS. Officially released in 2010, it has quickly established itself with services heavily targeting artificial intelligence, IoT and analytics.
In addition to being backed by Microsoft, and seamlessly integrating with existing Microsoft products, Azure competes with AWS in a few areas: hybrid support, security and platform as a service (PaaS) offerings.
For instance, Microsoft equipped Azure to offer plenty of hybrid cloud support. Not only does Azure make moving to the cloud a smooth transition, but it offers help in managing hybrid clouds (e.g., Azure Stack, Hybrid SQL Server) on an ongoing basis.

Ace your interview: 5 cloud engineering principles you need to know
Cloud engineering requires talent in all the right areas—beyond just passing a coding challenge. To show the interviewer you have the right blend of expertise and can respond to the unexpected, make sure you’re comfortable with core cloud engineering principles. In this next section, we’re covering five of the most important elements of cloud design, deployment and maintenance.
Some say data stored in the cloud is more secure than on-premise solutions—78% of IT professionals would agree. At the same time, an overwhelming 91% of organizations are concerned about cloud security, according to a 2018 report.
Why they ask: To cope with security threats (e.g., data loss and leakage, confidentiality breaches), organizations want to know you’ll take action to protect cloud workloads. First and foremost, how do you prevent damage, whether from human error or cyber attack? What steps do you follow to recover data? What security tools, technologies and processes have you adopted and rely on?
- What types of security testing have you built out and automated to ensure the deployment of secure cloud-based applications?
- Talk about the barriers you’ve previously encountered when migrating to the cloud and what steps you took to resolve those challenges.
- What encryption solutions do you find most effective in protecting stored data?
- How would you solve for a lack of integration with on-premise security technologies?
- In the event of a data breach, what’s the appropriate incident response process?
DevOps: a by-product of Agile paving the way for better communication, collaboration and automation. Ultimately, faster development and shorter product life cycles. DevOps and cloud computing bring their own benefits to the table—combining the two only complement each other’s strengths for even greater impact. In fact, companies using DevOps in the cloud report an 81% increase in software delivery performance.
Why they ask: Cloud solutions and DevOps go hand in hand. Knowing this, organizations may aim to uncover your level of understanding of how DevOps methods apply to cloud engineering. For instance, what’s the right balance of the two based on company size, team structure and goals?
- What DevOps tools have you previously used and which ones do you prefer?
- Explain your process for integrating containers into the DevOps process. How do you evaluate application needs to make these decisions?
- What processes have you automated previously and why? What was the outcome?
- Tell me about a time you guided developers to implement DevOps practices as they relate to the cloud.
- Why and how would you set up a continuous integration and continuous delivery pipeline?
Managing availability is top of mind for many companies operating in the cloud. Just because cloud platforms promise to deliver 99.99% availability, doesn’t make a company any less prone to unplanned failures or outages. For instance, lightning triggered an automatic shutdown of hardware at an Azure data center in 2018. Earlier that same year, an entire AWS data center failed.
Why they ask: Asking about availability helps a company understand how you plan on providing a fault-tolerant system, and how you’d handle failures. A company wants to understand your approach to availability—how you define needs, battle downtime and recover from the unexpected. Impressive past availability metrics? Don’t be modest.
- How do you determine availability requirements for a company?
- Explain the steps you took when a service provider failed to deliver the promised availability level. What was the outcome and how quickly did you recover?
- Do you think a multi-cloud approach is a viable solution for high availability? Why or why not?
- How do you use cloud architecture patterns for high availability?
- What processes would you automate to handle failure?
A major plus to operating in the cloud is the ability to scale without tacking on additional physical equipment at a higher cost. But with that growth, companies need to ensure that their systems and applications can handle increased load without crashing.
Why they ask: Questions about scalability shed light on how you’ll manage infrastructure according to fluctuating business needs. In the end, how will you help the company grow more rapidly without frequent crashes along the way? Do you know how to scale appropriately (vertical vs. horizontal vs. diagonal), avoid downtime and add (or remove) cloud provider services as needed?
- What steps do you take to monitor traffic?
- How do you plan for unexpected traffic spikes?
- Have you ever had to adjust cloud services based on the level of service needed? Why did you make this call?
- What’s your experience with load balancers?
- How have you tested for scalability in the past to prevent bottlenecks?
When things go south, from loss of power to cyber attacks, it’s important to have solid cloud storage and recovery solutions in place to restore compromised data. Tailoring disaster recovery plans to company needs is a must for fast recovery. After all, it’s not uncommon for companies to house some, if not all, sensitive business-critical data in the cloud.
Why they ask: When an interviewer asks about disaster recovery, they’re interested in how you’ll safeguard and retrieve its data—and how long it’ll take. What best practices do you follow when responding to disasters? How might you tailor recovery solutions for the company?
- Tell me about a disaster recovery plan you’ve built out and implemented.
- What steps did you take to recover from a disaster?
- How often do you test disaster recovery plans?
- What orchestration and automation tools have you used to recover data?
- Talk about your experience merging cloud-native backup with disaster recovery.
