  • 1.5d: Infrastructure audit of 82 services (ServerDiff.sh)
  • 1.5d: Create cloud architecture diagram.
  • 1.5d: Compliance check of 2 clouds (6 hypervisors, 6TB memory).
  • 1d: Cloud installations.
  • 0.5d: Stability check.
ACTION RESULT OK/KO
Activate maintenance for n/2-1 nodes or 1 node if 2 nodes. All resources are started.
Un-maintenance all nodes. Power off n/2-1 nodes or 1 node if 2 nodes, different from the previous test. All resources are started.
Power off all nodes simultaneously. Power on all nodes simultaneously. All resources are started.
  • 1.5d: Cloud automation study.

  • Formalize infrastructure for flexibility and reduced complexity.
  • Utilize customer-location tracking name server like GDNS.
  • Use minimal instances with a network load balancer like LVS.
  • Compare prices of dynamic computing services, beware of tech lock-in.
  • Employ efficient frontend TLS decoder like HAPROXY.
  • Opt for fast HTTP cache like VARNISH and Apache Traffic Server for large files.
  • Use PROXY with TLS decoder like ENVOY for service compatibility.
  • Consider serverless services for standard runtimes, mindful of potential incompatibilities.
  • Employ load balancing or native services for dynamic computing power.
  • Use open-source STACKs where possible.
  • Employ database caches like MEMCACHED.
