Technical articles. No filler.
FrankenPHP merges the web server and PHP into one binary, and its worker mode keeps Laravel booted in memory so requests per second multiply several times, provided your code does not leak shared state between requests.
Galera replicates every transaction synchronously across three MariaDB nodes, so a node failure loses no data and stops nothing, at the cost of an extra millisecond or two per write and some discipline in how the application writes.
Every PostgreSQL connection is a separate process using around 10MB, so PgBouncer in transaction mode multiplexes thousands of application connections onto about 20 real ones, multiplying what a 4GB server can handle without new hardware.
PostgreSQL logical replication streams row changes through a publication and a subscription to a live second server, even one on a newer major version, which makes it the right tool for upgrades and migrations with only seconds of downtime.
A practical continuity plan takes five steps: price each system's downtime per hour in riyals, rank systems with recovery time and point targets, keep backups and passwords off the server, assign four roles, and run a two-hour yearly exercise.
One systems engineer costs 240,000 to 360,000 SAR a year, and round-the-clock coverage takes four. For a mid-size company, one in-house developer plus managed infrastructure delivers wider coverage at lower cost and removes single-person risk.
Finance signs off on a server request when it sees the full annual cost including VAT, a comparison with two alternatives, a business-language justification and an official quote. Download the quote from the configurator before paying, then divide by 365.
A strong hosting RFP pins data residency inside the Kingdom, an SLA written into the contract with credits, backups with retention and restore targets, evidence-based NCA compliance, and an exit clause that guarantees data handover within 30 days.
Lock-in builds through proprietary services, egress fees and closed export formats. You avoid it with standard tools like Docker, PostgreSQL and S3, open-format backups held outside the provider, a yearly migration test, and contract clauses that guarantee your data handover.
