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)
