You can take a few steps to select a reliable DevOps services provider, starting from identifying business goals and ongoing plans, followed by studying the net and platforms for potential teams, and finalized by a personalized interview with a prepared list of questions.
First, you should do your homework and understand your company's goals. Then, you can create an RFP (request for proposal) listing all the necessary information, metrics, and criteria for selecting a suitable DevOps company. For example, you may include evaluation points like tech capacities, years of experience, tech stack used, portfolio, online presence, completed projects, and more to compare potential DevOps vendors.
In the next step, by checking platforms such as Clutch and GoodFirms listing specialized DevOps services providers, you can select around 5 teams for further dialogue. During the personal interview, you should pay close attention to the level of the team’s involvement, how they show their expertise, communication flow, and transparency. Check out how the team works, what technologies and methodologies are used, security standards, etc.
