Sound familiar?
- ▸ TempDB latch contention spiking PAGELATCH waits on pages 2:1:1 and 2:1:3 — the standard "more TempDB files" advice didn't fix it.
- ▸ Always-On AG sync replica lag blocking commits — the secondary can't keep up under peak write load, and you're seeing HADR_SYNC_COMMIT waits in the seconds.
- ▸ Licensing audit in 60 days and you're unsure whether Standard Edition covers your current Always-On / In-Memory / Columnstore usage — one false step is six figures.

Engagement Scope
What's included in a SQL Server consulting engagement?
Each engagement covers architecture review, performance triage, HA validation, and security hardening — measured against your actual workload, not a one-size template.
Migration Destinations
Where do you migrate SQL Server to?
The six most common SQL Server evolution paths we run — each with a different driver (licensing cost, cloud-native, open source, analytics). We pick the destination based on your actual workload, not on what saves the most license fees alone.
SQL Server → Azure SQL Managed Instance
Driver: Microsoft-native managed
Closest Microsoft-managed equivalent — near 100% T-SQL surface compatibility, SQL Agent, cross-DB queries, CLR. Cutover via DMS or backup/restore. We solve the network-isolation and time-zone-converter gotchas.
SQL Server → Aurora PostgreSQL
Driver: Licensing cost reduction
AWS-managed PostgreSQL with SCT (Schema Conversion Tool) for T-SQL → PL/pgSQL conversion. Typical Enterprise licensing savings: $50-200k/year. We handle the procedural code, CDC sync, and application connection-string rotation.
SQL Server → Self-managed PostgreSQL
Driver: Open source + control
Move off Microsoft licensing entirely — Babelfish (T-SQL on PG) or full conversion. Best when you have DBA capacity in-house and want predictable open-source TCO without vendor lock-in.
SQL Server → Azure SQL Database (PaaS)
Driver: Serverless / DTU pricing
Different from Managed Instance — single-database, serverless option, automatic tuning. Best fit for variable-workload apps where Hyperscale or DTU-based pricing reduces costs vs an instance you own 24/7.
SQL Server → MySQL / MariaDB
Driver: Web-stack consolidation
Schema and procedural conversion via SQLines or custom tooling. Best fit when SQL Server is the odd one out in a LAMP-style stack and the workload is OLTP-only with no heavy CLR / SSIS dependencies.
SQL Server → Snowflake / Synapse
Driver: Analytics decouple
Move reporting/BI workloads off OLTP — Snowflake (cloud-agnostic) or Synapse (Azure-native). Typical outcome: 10-50× faster dashboards and OLTP latency drops as analytical queries leave the primary.

How JusDB SQL Server Consulting compares to alternative models.
Standard cloud management and generic IT contractors lack deep SQL Server engine internals, NUMA awareness, and continuous DBRE reliability ownership. Here is how our certified SQL Server specialists compare:
| Evaluation Vector | JusDB DBRE | In-House DBA | Legacy Agency | Developer Generalist |
|---|---|---|---|---|
| Always On Availability Group Architecture | Multi-subnet WSFC cluster design, synchronous and asynchronous commit balancing, quorum witness optimization (Cloud/File Share), and automated failover verification. | Basic single-subnet setup vulnerable to split-brain, lease timeout stalls, and unmonitored redo queue latency on secondaries. | Generic template AG deployments without log throughput sizing, synchronous HADR_SYNC_COMMIT latency modeling, or cross-datacenter DR. | Attempts application-level failover or manual connection string swapping without WSFC quorum fencing, causing extended outages. |
| TempDB Allocation & Latency Tuning | Proportional fill calibration, equal file sizing matched to logical cores/NUMA nodes, trace flags 1117/1118, and memory-optimized table variable acceleration. | Single TempDB file or arbitrary counts on shared OS storage, causing severe PAGELATCH_UP waits on PFS, GAM, and SGAM allocation bitmaps. | Applies outdated 'one file per core' rules blindly across high-core systems, multiplying file allocation latch contention and checkpoint overhead. | Treats TempDB like a standard user database, creating uncontrolled #temp tables inside nested loops that saturate shared storage IOPS. |
| Query Store Plan Regression Forensics | Automated regression capture, forced plan stabilization, parameter sniffing eradication (OPTIMIZE FOR UNKNOWN), and Intelligent Query Processing telemetry. | Manual, reactive plan inspection after production alerts fire; struggles with plan cache bloat and parameter sensitivity issues. | Relies on heavy SQL Profiler and server traces that add 15%+ CPU overhead and miss historical plan transitions. | Leaves Query Store disabled or at default retention; resorts to clearing the entire plan cache with DBCC FREEPROCCACHE during slowdowns. |
| NUMA & MAXDOP Memory Ergonomics | Soft-NUMA partition mapping, MAXDOP calibration per socket, Cost Threshold for Parallelism (CTFP) right-sizing, and Buffer Pool / LPIM governance. | Default MAXDOP 0 or arbitrary instance caps without NUMA boundary awareness, causing cross-node foreign memory access and scheduler stalls. | Applies static legacy rules across high-core virtualized hypervisors, causing CXPACKET thread exhaustion and coordinator bottlenecking. | Leaves max server memory unconfigured, allowing SQL Server to starve the host OS and trigger destructive Windows paging file swapping. |
| Disaster Recovery & RPO/RTO Validation | Continuous tail-log backup orchestration, automated CHECKSUM restore verification drills, point-in-time recovery (PITR) auditing, and sub-minute RTO. | Nightly native backup jobs without automated checksum validation or regularly tested multi-terabyte disaster recovery restore drills. | Relies on hypervisor VM snapshots that break SQL Server transaction log LSN chains and invalidate point-in-time database restoration. | Unscheduled manual SQL dumps stored on the local database volume, risking total permanent data loss during drive failures. |
| Enterprise Security & TDE Encryption | Transparent Data Encryption (TDE) with external Azure Key Vault / EKM, Always Encrypted with secure enclaves, granular RBAC, and SOC 2 / ISO 27001 audit logging. | Native TDE with database master keys stored locally on the same instance without centralized key lifecycle or rotation protocols. | Shared 'sa' credentials, unencrypted TLS TDS endpoints, and overly broad sysadmin memberships assigned across development teams. | Hardcoded plaintext database credentials in application configs communicating over unencrypted public IP addresses. |
SQL Server Engine Failure Modes
Critical SQL Server Outage Modes We Eliminate
High-concurrency SQL Server environments face severe availability and latency risks when allocation bitmaps choke TempDB, asymmetric cluster heartbeats drop AG availability, or unparameterized queries flood the plan cache. Our DBREs resolve these breakdown modes:
TempDB Page Allocation Latch Contention (PAGELATCH_UP on PFS/GAM/SGAM)
High concurrency creates heavy contention on Page Free Space (PFS), Global Allocation Map (GAM), and Shared GAM (SGAM) allocation bitmaps in TempDB. Worker threads block with PAGELATCH_UP waits, stalling transactions across the entire instance.
JusDB configures equal-sized TempDB data files mapped to NUMA topology, enforces trace flags 1117 and 1118, pre-allocates uniform extents, and transitions heavy temporary workloads to memory-optimized table variables.
Asymmetric Cluster Heartbeat Loss Causing AG Split-Brain / Lease Timeout
Transient network packet loss or OS scheduling delays interrupt the SQL Server lease thread heartbeat between Windows Server Failover Clustering (WSFC) and the Availability Group engine, triggering premature failover or cluster split-brain.
JusDB calibrates LeaseTimeout, HealthCheckTimeout, and SameSubnetThreshold settings, isolates WSFC heartbeat networks, establishes cloud quorum witnesses, and configures automated non-blocking health checks.
Unparameterized Query Ad-Hoc Plan Cache Bloat
Ad-hoc application queries concatenating literal values generate unique execution plans for each execution, rapidly consuming gigabytes of the buffer pool for single-use plans and starving data pages from memory.
JusDB enables Optimize for Ad Hoc Workloads, forces parameterization via plan guides and Query Store forced plans, audits application ORM query patterns, and recovers buffer pool memory for active working sets.
Our SQL Server DBREs execute zero-impact diagnostic DMV queries to isolate TempDB latch allocation bottlenecks and historical Query Store plan regressions without introducing locks:
Inspects wait statistics for allocation page latch bottlenecks (PFS/GAM/SGAM) across TempDB data files to identify worker thread contention.
SELECT wait_type, waiting_tasks_count, wait_time_ms FROM sys.dm_os_wait_stats WHERE wait_type LIKE 'PAGE%LATCH%';
Queries Query Store DMVs to isolate queries experiencing plan regressions with the highest average execution duration for forced plan stabilization.
SELECT q.query_id, qt.query_sql_text, p.plan_id, rs.avg_duration FROM sys.query_store_query q JOIN sys.query_store_plan p ON q.query_id = p.query_id JOIN sys.query_store_runtime_stats rs ON p.plan_id = rs.plan_id JOIN sys.query_store_query_text qt ON q.query_text_id = qt.query_text_id ORDER BY rs.avg_duration DESC;
