- 11. • The services are easy to replace. • Services are organized around capabilities, e.g., user interface front-end, recommendation, logistics, billing, etc. • Services can be implemented using different programming languages, databases, hardware and software environment, depending on what fits best. microservice architecture ƗƗƗ Ɨ Ɨ ƗƗ Ɨ Ɨ Ɨ Ɨ Ɨ

- 51. Ɨǽ “The right tests should be the same in all your environments.”
- 52. Ɨǽ “I didn't have time to create a slim image, so I created a fat one instead.”
- 53. Ɨǽ “The right image needs at least 5 kisses” kiss = keep an image s…, smart ass slim secure speedy stable set
- 54. SLIM Start with the smallest minimal image you can find and trust. Remove compile time dependencies. Remove packages you don’t need. Squash layers to reduce size. Run stats for the image. habitus.io blog.cloud66.com Ɨǽ
- 58. SECURE Remove all the secrets. Patch to the latest security updates. Run the image with the right UID. Test the image. https://github.com/docker/ docker-bench-security Ɨǽ
- 60. SPEEDY Optimize code. Memory and cpu usage. One process. Load testing. Ɨǽ
- 62. STABLE Lock the image version. Lock the runtime version(s). Tag your image. Proper logging. Ɨǽ
- 64. SET Use volumes wisely, use external services for persistency, don’t abuse host system. Loosely coupled. Remove things which are hard to maintain in production. Ɨǽ

- 74. Choose your platform wisely.
- 77. LIFECYCLE Have an image guideline. Create a workflow using the same image in all the software cycle stages. From design to production mimic the environment. Test heavily. Ǻ
- 79. ORCHESTRATION Provisioning nodes. Networking. Isolation of services. Self healing. iOi = Infrastructure on Infrastructure. Ǻ
- 81. DISCOVERY Find your services and datasources with minimal code change. Versioning of running services. Automagically update discovery when services come and go. Ǻ
- 83. SCALING/SCHEDULING Scale your service (= more running containers). Scale your nodes. Scale your on/off jobs. Failover groups. Hybrid infrastructure. Load balancing. Ǻ
- 85. DATA MANAGEMENT Backup and restores. Clustering. Verify your backups. Ǻ
- 87. MONITORING Get all the statistics of resources (mem/load/net/res) used. Aggregating of logs. Key debugging ingredient. Ǻ ǟ
- 89. SECURITY Node and Engine level. Intrusion detection and prevention systems. DoS protection. Firewall. Segregate container groups Verification of images. Ǻ Ǻ
- 90. Choose your platform wisely.
- 91. When you get DevOps, Testing, Microservices architecture right and creating the right minimal lovable Image and having the right platform to run containers. Happy Camper. ǽ
