Amazon has announced that it has been chosen to provide Symantec with strategic infrastructure services for the majority of cloud workloads. Symantec will use AWS to deliver cloud security to global customers, as part of a continuing relationship between the two companies.

Not only is Symantec using AWS for cloud-based infrastructure operations, it will also use the AWS Marketplace to deliver security services. The company has constructed a data lake on AWS, collecting data from 175 million endpoints and 57 million attack vectors, according to the announcement by Amazon. This provides Symantec with a constantly updated global security dataset amounting to tens of terabytes every day.

Raj Patel, Vice President, Cloud Platform Engineering at Symantec, noted that his company is committed to protecting cloud data, as well as leveraging cloud technology to deliver Symantec services. “Our cloud-first approach to engineering requires a highly scalable and reliable infrastructure that helps our team deliver faster time-to-market and ensure that security remains our top priority,” he said.

“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 Defense strategy.”

Symantec selected AWS for scale, as well as cloud services that include data analytics, machine learning, and containerization. The company is moving legacy applications to the cloud, as well as building new, cloud-native and hybrid applications.

Just last month, it seemed that Microsoft was winning the battle for Symantec’s cloud business, when the announcement was made that Symantec had selected Microsoft to deliver Norton security products through the Azure cloud. This decision was made as a part of Symantec’s strategic decision to adopt hybrid cloud strategies, and is expected to be followed with the addition of Norton security software to the Azure e-commerce marketplace, to help streamline the online purchase of Norton software.

Earlier this month, Symantec released a positive Q2 report for FY 2018, reporting a 26% increase in revenues over the previous year and a 47% increase in operating income. These results were attributed to acquisition and integration activities, as well as the March updating of the company’s cloud security products portfolio.
