Mainstream is a forward-thinking technology company with its focus 100% on the cloud. We embraced the cloud back in 2005 and never looked back. Since then, we have grown in multiple directions, in many ways – building the largest team of cloud experts in the SEE region and a data centre ecosystem that spans six countries in Europe. Most importantly, we have built long-lasting relationships with 200+ customers region-wide.
Combined with our multi-cloud knowledge, our state-of-the-art HA infrastructure provides our enterprise clients with a turnkey solution for their digital projects. Whether that be Cloud Hosting, Infrastructure as a Service (IaaS), Application Development and Migration, Backup, and Disaster Recovery, Mainstream can help you eliminate complexity to make the most from your cloud investment.
We support all major public cloud platforms (Microsoft Azure, Amazon Web Services, Google Cloud) and deliver the highest level of performance with our Mainstream Enterprise and Managed Hosting platforms. What truly makes us different, though, is our value-first approach to cloud computing. We design and implement client-specific solutions to ensure you get maximum value from the cloud. Rather than purely implement, we strategize. Our experts dig deep into our clients' IT environments, identifying the weak spots, as well as opportunities, and designing custom solutions to address them.
From IT infrastructure optimization to cloud management, our enterprise infrastructure, cloud expertise and solutions ensure growth – now and in the future.
