Introduction The Elastic Load Balancing (ELB) service provides you with Amazon CloudWatch metrics (HealthyHostCount and UnhealthyHostCount) to monitor the targets behind your load balancers. Although the unhealthy host count metric gives the aggregate number of failed hosts, there is a common pain point when you create an alarm for unhealthy hosts based on these metrics. […]

CloudFront now Supports ECDSA Certificates for HTTPS Connections to Origins

See how you can now use Amazon CloudFront to negotiate HTTPS connections to origins using Elliptic Curve Digital Signature Algorithm (ECDSA). ECDSA uses smaller keys that are faster, yet, just as secure, as the older RSA algorithm. The smaller keys will also increase the number of TLS handshakes that your origins can process per second, thereby saving compute cycles and reducing your cost of cryptography.
