TRAINING
Cloud Native Install
CLOUD LAB
Presenting my LAB project.
CLOUD Audit
Created ServerDiff.sh for server audits. Enables configuration drift tracking and environment consistency checks.
CLOUD Migration Example
- 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
- .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 simultaneous all nodes. Power on simultaneous all nodes. | All resources are started. |
- 1.5d: Cloud automation study
- 1.5d: Develop 6 templates (2 clouds, 2 OS, 8 environments, 2 versions)
- 1d: Create migration diagram
- 1.5d: Write 138 lines of migration code (MigrationApp.sh)
- 1.5d: Process stabilization
- 1.5d: Cloud vs old infrastructure benchmark
- .5d: Unavailability time calibration per migration unit
- 5min: Load 82 VMs (env, os, application_code, 2 IP)
Total = 15 man-days
WEB Enhancement
- 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 service 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.
- Use queues for long batch.
- Use buffers for stability of real streams.

CLOUD NATIVE
- OFFICIAL STACKS
- DevSecOps :
High Availability (HA) with Corosync+Pacemaker
Typical Architecture
- Dual-room.
- IPMI LAN (fencing).
- NTP, DNS+DHCP+PXE+TFTP+HTTP (auto-provisioning), PROXY (updates or internal REPOSITORY).
- Choose 2+ node clusters.
- For 2-node, require COROSYNC 2-node config, 10-second staggered closing for stability. But for better stability choose 3+ nodes architecture.
- Allocate 4GB/base for DB resources. CPU resource requirements generally low.
Typical Service Pattern
- Multipath
- LUN
- LVM (LVM resource)
- FS (FS resource)
- NFS (FS resource)
- User
- IP (IP resource)
- DNS name
- Process (Process resource)
- Listener (Listener resource)
