Symantec will move the "vast majority" of its cloud workload to Amazon Web Services (AWS) after announcing a partnership with the cloud giant.
The vendor said it is making a "major operational move" to AWS, just a month after moving its Norton consumer business to Microsoft Azure.
Symantec said it selected AWS based on its pedigree serving some of the world's largest organisations.
Raj Patel, VP of cloud platform engineering at Symantec, said: "Our cloud-first approach to engineering requires a highly scalable and reliable infrastructure that helps our team deliver faster time-to-market and ensures that security remains our top priority.
"Symantec is committed to protecting the cloud generation through our leading security products, as well as leveraging the cloud to deliver our services.
"AWS's experience serving some of the most risk-sensitive enterprise customers was an important part of the decision to choose AWS as we execute on our enterprise integrated cyber-defence strategy."
The pair claim that their relationship is bi-directional, with Symantec also using the AWS marketplace as a route to market.
Symantec said the AWS platform allows it to develop new software and tools at a faster rate.
Mike Clayville, VP of worldwide commercial sales at AWS, added: "By taking advantage of the benefits of deploying their software on AWS, Symantec has been able to accelerate its pace of innovation, gain deeper insights through their company-wide data lake, and use that knowledge to make better-informed business decisions.
"Leading ISVs worldwide are moving core business applications to AWS for greater agility and efficiency, to reduce costs, and to leverage the security, reliability, and global infrastructure we offer.
"We look forward to working with Symantec to deliver world-class security to global customers."
