Telecom microservices are transforming Communications Service Providers (CSP) into Digital Service Providers (DSP). Microservices architecture breaks down complex IT systems into easily manageable components, offering agility, scalability, extensibility, and on-demand capabilities. This approach enables personalized and omnichannel experiences for telecom end users. Aerospike's real-time data platform provides high performance and future-proof scaling capabilities, making it a valuable asset in implementing microservices. Telecom microservices are widely used in Business Support Systems (BSS), Operations Support Systems (OSS), and network management, as well as enabling innovative services like real-time cross-sell/upsell in gaming and mobile commerce. Aerospike's highly scalable data platform has improved connections 10X and lookups by nearly 6X for a major Tier-1 telco customer while keeping operational costs low.
