The webinar “HITS in the cloud: elevate your SQL Server strategy with Azure Arc” delivered a practical, business‑focused playbook for modernising SQL Server estates across hybrid and multi‑cloud environments — emphasising unified management, automated compliance, flexible licensing, and observable, secure operations that let organisations turn legacy databases from liabilities into assets.
Azure Arc has matured from a niche hybrid control plane into a mainstream toolset that brings Azure management, policy and services to resources wherever they run. The webinar, hosted by Altron Digital Business and Microsoft South Africa and summarised in TechCentral, positioned Azure Arc as the central mechanism for modernising SQL Server without abandoning on‑premises control or compliance requirements. Key themes were governance, observability, licensing flexibility, and a pragmatic framework for modernisation labelled HITS (Highly available, Innovative, Transformative, Secure).
Microsoft’s product strategy is to make Arc the management plane for heterogeneous estates while charging separately for Azure services consumed through that plane. That distinction matters to IT buyers because Arc’s control plane is offered free but the add‑on services (monitoring, update management, Defender, policy guest configuration) are billed according to normal Azure pricing. This pricing model and its implications for patching, ESUs and pay‑as‑you‑go SQL licensing were discussed at length in the webinar and are confirmed in Microsoft’s documentation and pricing pages.
This changes how teams triage incidents: instead of manually running queries and drafting remediation steps, engineers can ask Copilot to summarise high‑priority alerts or suggest a prioritized list of queries — cutting mean time to detection and remediation.
That said, the real work is operational and financial discipline. Arc does not make problems disappear — it reframes them into centrally managed, billable Azure services. For IT leaders, the opportunity is to use Arc to reduce technical debt and accelerate innovation while instituting FinOps controls, least‑privilege identity governance, and staged migration pipelines.
Organisations that treat the webinar’s playbook as a pragmatic roadmap — start small, secure the estate, pilot observability and automation, then scale governance and cost controls — will be able to modernise their SQL Server footprint reliably. Those that copy the architecture without the operational guardrails risk escalating cloud bills, centralised configuration errors, and governance gaps.
Azure Arc is a valuable tool in the modern SQL Server toolkit. The webinar distilled a realistic path to bring legacy SQL servers into compliance, add modern observability, and give business leaders the assurance that modernisation can be controlled, measurable and strategic.
For readers planning next steps, treat Arc as a capability to be earned, not a one‑click cure: run a controlled pilot, validate licensing and ESU eligibility with your licensing partner, and build policy and FinOps guardrails before broad adoption.

Why Azure Arc matters for SQL Server today
SQL Server remains the backbone of transactional systems, reporting, and compliance for many organisations. Modern IT decisions are not only technical — they are strategic, affecting resilience, speed to market and regulatory risk. The webinar made three practical points that echo wider enterprise trends:- Hybrid reality: Many businesses will keep a mix of on‑premises, edge and cloud SQL instances for technical, regulatory or cost reasons. Azure Arc lets those servers appear and be managed as Azure resources, removing tool sprawl.
- Compliance and governance: Centralised policy, RBAC and guest configuration let teams apply GDPR, POPIA, CIS and NIST frameworks consistently, reducing audit risk and human error.
- Cost and licensing flexibility: By enabling pay‑as‑you‑go licensing for SQL Server via Arc and enabling ESU subscriptions for older SQL versions, Arc provides fiscal breathing room during staged modernisations. These features are available but have specific prerequisites and cost trade‑offs.
Azure Arc in practice: what the webinar covered
Onboarding, visibility and centralised control
Azure Arc presents non‑Azure resources in the Azure Resource Graph, so teams can:- Discover and inventory SQL Server instances across on‑premises, AWS, GCP and edge devices.
- Apply Azure Policy and role‑based access controls consistently.
- Surface performance and configuration telemetry inside Azure Monitor workbooks and dashboards.
Modernisation without “big bangs”
The common blocker for SQL modernisation is application dependency on specific SQL Server versions or paused upgrade cycles due to compatibility risks. Azure Arc enables a staged approach:- Assess readiness using Azure tools (Data Migration Assistant, DMS, and Arc readiness checks).
- Apply governance and remediation policies centrally to prepare targets.
- Migrate or refactor workloads into Azure SQL Managed Instance, Azure SQL Database, or keep them on‑prem with Arc and managed services.
Licensing and cost controls
Two licensing points from the webinar are especially relevant:- Pay‑as‑you‑go (PAYG) for SQL Server: Microsoft offers a consumption‑based SQL licensing option enabled via Azure Arc that lets organisations pay hourly for SQL Server usage on non‑Azure infrastructure. This is designed for scenarios where perpetual licences are unavailable or prohibitively expensive to maintain during transition. Microsoft’s Arc pricing page explains the PAYG options (Standard and Enterprise) and the mechanics for billing through Azure.
- Extended Security Updates (ESUs): For out‑of‑support versions such as SQL Server 2012/2014, Arc’s subscription model enables hourly ESU billing when instances are connected — a practical safety net to keep legacy systems secure while migration is planned. Microsoft’s SQL Server ESU documentation describes how Arc‑connected instances can receive ESUs as a subscription option.
Observability, automation and AI: Copilot in Azure
A standout thread from the webinar — and increasingly visible across Azure — is combining Arc’s unified telemetry with Copilot in Azure to make observability actionable. Copilot can:- Answer natural‑language questions about resource utilisation and availability.
- Suggest Kusto Query Language (KQL) snippets for deeper exploration of logs and metrics.
- Help generate remediation scripts, or create operational runbooks and tickets from workbooks.
This changes how teams triage incidents: instead of manually running queries and drafting remediation steps, engineers can ask Copilot to summarise high‑priority alerts or suggest a prioritized list of queries — cutting mean time to detection and remediation.
Governance and compliance at scale
Centralised governance was a repeated theme. Azure Policy, Guest Configuration, and RBAC together create:- Policy enforcement for new servers as they are onboarded.
- Auditable configuration drifts and guest OS baseline checks.
- Automatic remediation scripts for non‑compliant machines.
The HITS framework: practical and persuasive
HITS — Highly available, Innovative, Transformative, Secure — is a tidy mnemonic that helps translate cloud principles into SQL Server decisions:- Highly available: use Arc for central HA/DR oversight and plan failover to Azure SQL Managed Instance where appropriate.
- Innovative: leverage managed PaaS features (automated tuning, serverless options, Synapse integration) when the app can consume platform services.
- Transformative: modernise in phases using assessments and migration tools.
- Secure: enforce policy, ESUs, and Defender for Cloud across the estate.
Critical analysis — strengths, blind spots and operational risks
Azure Arc and the webinar’s playbook offer real strengths — but they come with caveats every buyer must weigh carefully.Strengths
- Unified control plane: Arc reduces tool sprawl by making on‑premises and multi‑cloud assets manageable from a single portal, simplifying governance and audits.
- Licensing flexibility: Pay‑as‑you‑go SQL licensing and Arc‑enabled ESU subscriptions turn capital licence burden into an operational expense with granular control. This helps in phased modernisation and temporary capacity spikes.
- Observability + AI: Integrations between Azure Monitor, workbooks and Copilot speed troubleshooting, generate actionable queries, and help less‑experienced staff navigate complex telemetry.
Risks and blind spots
- Ongoing operational costs: Arc’s control plane may be free, but the management services used through it (Update Manager, Monitor, Defender, Policy guest configuration) are billed separately. Patch and monitoring costs can scale quickly across hundreds or thousands of servers. Azure Update Manager, for instance, is charged for Arc‑enabled servers in most scenarios (roughly $5 per server/month under normal billing rules), so budgeting is essential.
- Network and latency considerations: Arc requires outbound connectivity to Azure endpoints. For highly restricted or air‑gapped environments, adopting Arc may introduce operational complexity or require proxies and special networking arrangements.
- Surface area for centralisation risk: A single control plane improves governance, but also concentrates risk. Identity misconfigurations, over‑privileged roles, or misapplied policies can have broad impact across the estate. Enforcing least privilege and using privileged identity management are mandatory guardrails.
- Vendor lock and platform dependency: While Arc supports multi‑cloud and on‑premises resources, many of the most powerful management benefits are realized in combination with Azure services. Organisations should weigh the balance between operational efficiency and long‑term portability.
- Complexity of migration: The webinar correctly framed migration as staged, but enterprises should plan for schema compatibility issues, application testing, and rollback plans. Underestimating the testing, performance baselining, and change management required is a frequent cause of modernisation delays.
Verifiability and caveats
Several claims in vendor or partner presentations can be technical shorthand. Where the webinar suggested “reclassify perpetual licenses to pay‑as‑you‑go,” readers should verify their specific licensing entitlements and procurement channels. Licensing rules vary by agreement type (EA, MPSA, CSP) and local distributor terms; a pay‑as‑you‑go reclassification can be subject to eligibility and administrative steps. Microsoft’s Arc pricing pages and licensing guides provide the mechanics, but every organisation should validate in writing with their licensing partner or Microsoft representative.Practical guidance: a short operational checklist
- Inventory and assess: Use agented discovery and application‑aware mapping to identify SQL Server versions, dependencies and data gravity.
- Prioritise by risk: Identify business‑critical instances, regulatory constraints and legacy apps that must be remediated first.
- Plan licensing and ESU strategy: Decide whether to move to PAYG, use Arc‑enabled ESU subscriptions, or retain perpetual licences with Software Assurance. Validate costs across 12–36 months.
- Automate governance: Build Azure Policy initiatives and guest configurations as code; include human approval gates for production impact.
- Pilot with observability: Onboard a subset of servers to Arc + Azure Monitor + Copilot to validate dashboards and auto‑remediation flows before large‑scale rollout.
- Monitor costs: Use Azure Cost Management and FinOps practices to detect zombie VMs, unexpected Update Manager charges, and growth in log ingestion costs.
What this means for South African and regulated markets
The webinar emphasised local realities: infrastructure constraints, regulatory regimes (POPIA), and tighter IT budgets. Azure Arc reduces the compliance friction of modernisation in these markets by enabling:- ESUs for legacy SQL without wholesale migration.
- Centralised policy enforcement to meet local data protection requirements.
- Cost models that align spending with actual usage, a key advantage for organisations that face unpredictable operational conditions.
Final verdict: practical, powerful — but plan for the ongoing bill
The “HITS in the cloud” webinar was useful because it focused on the practical steps organisations can take to modernise SQL Server estates without sacrificing governance or control. Azure Arc unlocks a compelling combination of hybrid manageability, pay‑as‑you‑go licensing, and operational observability — and Copilot in Azure turns telemetry into conversational, actionable insights.That said, the real work is operational and financial discipline. Arc does not make problems disappear — it reframes them into centrally managed, billable Azure services. For IT leaders, the opportunity is to use Arc to reduce technical debt and accelerate innovation while instituting FinOps controls, least‑privilege identity governance, and staged migration pipelines.
Organisations that treat the webinar’s playbook as a pragmatic roadmap — start small, secure the estate, pilot observability and automation, then scale governance and cost controls — will be able to modernise their SQL Server footprint reliably. Those that copy the architecture without the operational guardrails risk escalating cloud bills, centralised configuration errors, and governance gaps.
Azure Arc is a valuable tool in the modern SQL Server toolkit. The webinar distilled a realistic path to bring legacy SQL servers into compliance, add modern observability, and give business leaders the assurance that modernisation can be controlled, measurable and strategic.
For readers planning next steps, treat Arc as a capability to be earned, not a one‑click cure: run a controlled pilot, validate licensing and ESU eligibility with your licensing partner, and build policy and FinOps guardrails before broad adoption.
