Alibaba Cloud Server Load Balancer vs Progress Kemp LoadMaster

Alibaba Cloud Server Load Balancer has no write-up on Specifiction yet; its figures are above.

Progress Kemp LoadMaster is an application delivery controller and server load balancer for managing application and user traffic. Its routing and delivery features include Layer 4 and Layer 7 balancing, persistence, health checks, SSL acceleration and offloading, and rule-based content switching. An integrated WAF covers protections such as OWASP Top Ten risks, SQL injection, cross-site scripting, and denial of service; other access controls include reverse proxy, single sign-on, pre-authentication, dual-factor authentication, IPS, and SSL bridging. GEO policies can direct clients to datacenters by location or proximity and support failover and failback. Progress offers hardware, virtual, and cloud forms, with on-premises and cloud deployment options. Cloud licenses can be pay-per-use, charged only for usage consumed, or perpetual BYOL. The temporary trial costs nothing for 30 days on the VLM-MAX model with Enterprise Plus Support, including ESP, WAF, and GEO. When that license expires, LoadMaster ceases to function; some features may also be lost if a permanent license has a different support tier.
