Quick answer: An AWS managed service provider (MSP) is an outside company that runs the daily work in your AWS cloud environment. That work includes monitoring systems, fixing problems, applying updates, and controlling costs. Your company still owns its data and its compliance duties.
Key Takeaways
- An AWS managed service provider handles daily cloud operations, but your company stays accountable.
- AMS is AWS’s own service. An AWS MSP is an independent partner.
- AWS validation verifies a provider’s operational processes but does not guarantee that its services are suitable for your specific workloads.
- Get access rules, responsibilities, and exit terms in writing before you sign.
Why Companies Use an AWS Managed Service Provider
Moving to AWS doesn’t mean AWS takes care of everything. Under the AWS shared responsibility model, AWS secures the infrastructure that runs its cloud services: the host operating system, the virtualization layer, and the physical data centers. The customer handles the guest operating system, security patches, application software, and firewall settings.
Put simply, AWS secures the building. You secure what you build and run inside it. That work never stops. Someone has to patch servers, watch alerts, and review access, and many teams hand part of that job to an AWS managed service provider.
What Does an AWS MSP Do?
A contract defines the scope of the work, and a service level agreement (SLA) sets response times. Most contracts cover these tasks:
| Task | What it means |
| Monitoring | Watching your systems around the clock and sending alerts when something breaks |
| Incident response | Fixing outages or errors, then reporting what happened |
| Patching | Installing security updates on servers and software |
| Backups | Copying your data and testing that it can be restored |
| Access reviews | Checking who can log in and what each person can change |
| Cost reviews | Finding unused or oversized resources you’re still paying for |
Many providers also review your setup against the AWS Well-Architected Framework, a set of best practices that AWS publishes. It started with five pillars: operational excellence, security, reliability, performance efficiency, and cost optimization. AWS added sustainability as a sixth pillar in late 2021.
One point is easy to miss: an AWS managed service provider takes on tasks, not accountability. AWS notes that managing and verifying IT controls is a shared duty too. If an auditor asks questions, your company is the one that answers.
AWS MSP vs. AWS Managed Services (AMS)
The names sound alike, but they are different offerings.
- An AWS MSP is an independent partner company.
- AWS Managed Services (AMS) is AWS’s own offering, delivered by AWS staff.
AMS comes in two plans. Accelerate covers monitoring, incident management, and security. Advanced adds landing zone management, infrastructure provisioning, access management, and endpoint security. A landing zone is a pre-built, multi-account AWS setup with security and logging already in place. When you review a proposal, check which of the two it includes.
Three Ways to Run AWS Operations
| Option | Who does the work | Good fit for | Watch out for |
| In-house team | Your own staff | Teams that already have cloud skills | Hiring, training, and on-call coverage |
| AMS | AWS staff | Teams that want AWS to run operations directly | Covers AWS environments only |
| AWS MSP partner | An outside firm | Teams that also need migration help or support beyond AWS | Quality varies from firm to firm |
What Working With an AWS MSP Looks Like
Most engagements with an AWS managed service provider follow a similar pattern, though the details vary by provider.
- Assessment: The provider reviews your current accounts, workloads, and security settings. This step often turns up quick fixes, such as unused resources or overly broad permissions.
- Onboarding: Your team grants access, the provider connects its monitoring tools, and both sides agree on runbooks. A runbook is a written, step-by-step guide for handling a specific task or incident.
- Ongoing operations: The provider handles daily tasks and reports against the SLA. Regular review meetings cover recent incidents, costs, and planned changes.
How to Check Whether an AWS MSP Is Validated
Any IT firm can call itself an AWS managed service provider. Some have also earned a formal designation through the AWS MSP Program. To qualify, a partner must pass a third-party audit of its technical skills and business health. New applicants complete a pre-assessment before the full audit, and AWS runs performance-based renewals in the years between full audits.
What validation tells you: the provider’s processes passed a standard review.
What it doesn’t tell you: whether the provider is right for your workload.
AWS offers a public search tool for finding validated MSP partners. Use it to confirm a provider’s claim before you sign.
Questions to Ask an AWS Managed Service Provider Before You Sign
- How do you measure service levels? Ask for a sample report. The AWS MSP audit checklist reviews SLA documentation and sample service reports.
- Who can access admin and root accounts? Verify that access is assigned to individual users and that all sessions are logged, rather than relying on shared credentials.
- What happens during a major outage? Ask who you call, how fast they respond, and when they escalate issues to AWS Support.
- Which tasks stay with us? Get the split in writing and map it to the shared responsibility model.
- Do you support regulated workloads? If you handle government data, ask about experience with AWS GovCloud (US).
- Who owns the documentation? If you leave, you need the runbooks and infrastructure-as-code templates.
- How is pricing calculated? Per-account, per-resource, and percentage-of-spend models change differently as you grow.
When You May Not Need an AWS MSP
Hiring an AWS managed service provider isn’t always the right call. Some teams get better value from other options. You may not need one if:
- Your workload is small and stable, and one experienced engineer can run it.
- You want to build cloud skills inside your team first.
- You only need help with a single project, such as a migration.
Need Help With Your AWS Environment?
If you’re deciding whether to keep AWS operations in-house or bring in outside help, it helps to talk it through with people who do this work every day. Red River provides AWS cloud managed services for commercial and public sector organizations, from migration planning to ongoing operations.
