Pegasystems has deepened its 7-year-old relationship with Amazon AWS, and also has teamed up with Microsoft Azure, company officials said Tuesday. The deals are part of a series of planned partnerships aimed at giving Pega's clients choice in their cloud environment and avoiding lock-in. Pega last month inked an agreement to deliver Pega software on Pivotal Cloud Foundry. "These partnerships enable us to optimize all of our solutions within different cloud provider environments," said Ying Chen, head of product strategy at Pegasystems.
