About Josh Palmer
I'm Josh Palmer, Head of Content at DoiT, where I split my time across multiple business units including DoiT Cloud Intelligence, PerfectScale (Kubernetes cost optimization), and SELECT (Snowflake, Databricks, and BigQuery cost optimization). Before DoiT, I spent four and a half years at OnBoard building content for a board intelligence platform used by 6,000+ organizations, and before that, two years as Content Marketing Manager at Zylo, a SaaS management platform.
My personal pageTL;DR
- A managed service provider (MSP) is a third-party company that remotely manages a business's IT infrastructure, systems, or cloud environment on an ongoing, subscription basis, proactively rather than reactively.
- Core MSP services span monitoring, patching, security operations, cost optimization (FinOps), backup/disaster recovery, and DevOps automation.
- Pricing is typically a flat monthly retainer, a percentage of managed spend, or a per-device/per-user rate.
- MSPs differ from MSSPs (security-only) and CSPs (infrastructure/hosting only); most businesses end up using some combination of all three.
- The global managed services market was valued at $401.2 billion in 2025 and is projected to reach $437.3 billion in 2026, growing at a 9.9% CAGR through 2033, driven largely by cloud complexity and AI workload management.
- MSPs aren't AWS-only. Microsoft and Google Cloud run their own MSP validation programs too, and most enterprise MSPs today operate across all three.
- For cloud-specific environments, look for an MSP independently validated by the provider itself: AWS runs the AWS MSP Program (getting harder to pass as of VCL 8.0), Microsoft runs Azure Expert MSP, and Google Cloud runs its own MSP Initiative.
A managed service provider (MSP) is a company that takes over the day-to-day operation of a business's IT systems (infrastructure, networks, applications, cloud environments, or some combination of all three) for a recurring fee, instead of a business staffing and running that operation internally. The defining trait isn't the specific services on the menu; it's the model: proactive, ongoing, and outcome-accountable, rather than a technician who shows up after something breaks.
That distinction matters more than it sounds. A traditional "break-fix" IT vendor gets paid when something goes wrong. An MSP gets paid whether anything goes wrong or not, which only works as a business model if the MSP is actively preventing problems, not waiting for them.
What Does a Managed Service Provider Actually Do?
MSP is a broad category, but most providers' work breaks down into the same recurring functions:
- Monitoring and alerting. Continuous visibility into system performance, uptime, and security events, with alerts before small issues become outages.
- Patch and configuration management. Keeping servers, endpoints, and software current without manual, per-device upkeep.
- Security operations. Identity and access management, vulnerability scanning, and incident response, handled either directly or subcontracted to a dedicated MSSP.
- Cost optimization (FinOps). For cloud-focused MSPs specifically, rightsizing resources, managing commitment discounts, and eliminating idle spend. The specifics differ by cloud: see DoiT's own AWS, Google Cloud, and Azure cost optimization programs for how that plays out on each.
- Backup and disaster recovery. Automated backup policies and tested recovery procedures, so an outage doesn't become data loss.
- Help desk and end-user support. First- and second-line support for employees, freeing internal IT from ticket queues.
- DevOps and automation. Infrastructure-as-code, CI/CD support, and increasingly, agentic automation that resolves issues without a human ticket at all.
Which of these a given MSP actually covers varies widely. Some are IT generalists supporting on-prem networks and end-user devices for small businesses. Others specialize entirely in one cloud provider's stack. See What Are AWS Managed Services? for how that looks specifically on AWS.
How Does the MSP Pricing Model Work?
MSPs typically price one of three ways:
| Model | How it works | Best fit |
|---|---|---|
| Flat monthly retainer | Fixed fee scoped to the environment's size and the services included | Predictable environments, budget certainty |
| Percentage of managed spend | Fee scales with cloud or infrastructure spend under management | Cloud-native environments with variable usage |
| Per-device / per-user | Fee scales with endpoint or seat count | Smaller businesses, straightforward IT footprints |
Get a scoped quote directly from providers before comparing price alone. Cost depends heavily on environment size, the depth of 24/7 coverage required, and how much security or cost-optimization work is bundled in versus billed separately.
MSP vs. In-House IT vs. Break-Fix Support
| In-House Team | Break-Fix Vendor | Managed Service Provider | |
|---|---|---|---|
| Coverage | Business hours, unless staffed 24/7 | Reactive, on request | 24/7 monitoring and response, by design |
| Payment trigger | Fixed headcount cost | Paid per incident | Paid on a recurring basis regardless of incidents |
| Incentive alignment | Aligned, but capacity-constrained | Misaligned: more breakage can mean more billable work | Aligned: fewer incidents is the goal, not the enemy |
| Specialization | Generalist, built over time | Varies, often generalist | Engineers certified specifically in the covered stack |
| Compliance evidence | Built and maintained internally | Rarely offered | Often pre-built into the provider's audited processes |
Break-fix is largely a legacy model at this point; the real decision for most growing companies is in-house versus managed, or, more commonly, some hybrid of the two: an internal platform team paired with an MSP for 24/7 operations and specialized workstreams like security or FinOps.
MSP vs. MSSP vs. CSP: What's the Difference?
These three acronyms get used almost interchangeably, but they cover different scopes:
- MSP (Managed Service Provider): Broad, ongoing IT operations, including networks, systems, help desk, and often security and cost management layered in.
- MSSP (Managed Security Service Provider): Security specifically, covering threat monitoring, firewall management, and incident response, usually backed by a 24/7 security operations center (SOC).
- CSP (Cloud Service Provider): The infrastructure itself: compute, storage, and platform services (AWS, Azure, Google Cloud). A CSP hosts the environment; it doesn't operate it for you.
In practice, most MSPs resell or manage CSP capacity and bundle MSSP-style monitoring on top, so the lines blur. When evaluating a provider, ask directly which of these three functions they actually own versus subcontract.
Are All MSPs the Same? Generalist vs. Cloud-Specialized Providers
Not even close. Two broad categories matter most for a growing company choosing between them:
Generalist MSPs support a mix of on-prem, hybrid, and cloud environments across whatever mix of vendors a customer runs, often oriented around end-user support and network management for small and mid-size businesses.
Cloud-specialized MSPs focus on one or more hyperscalers (AWS, Azure, or Google Cloud) and go deep on that provider's specific services, cost model, and compliance requirements rather than covering everything shallowly. That specialization is validated externally by the cloud provider itself, not just claimed in a sales deck: see What Are AWS Managed Services? for how AWS's own managed offering (AMS) differs from a third-party AWS MSP, and what to look for in either.
If most of a company's infrastructure already sits on one cloud, a specialized provider validated on that specific stack is almost always the stronger fit over a generalist spreading attention across every environment type. Many enterprise MSPs, DoiT included, hold validation across more than one cloud simultaneously, since most customers today run at least some multi-cloud footprint.

How Do AWS, Azure, and Google Cloud Each Validate Their MSPs?
"MSP" isn't a self-applied label with any of the three major hyperscalers. Each runs its own independent audit before a partner can claim the designation, though the mechanics differ:
| Cloud | Program | How partners are validated |
|---|---|---|
| AWS | AWS MSP Program | An audited Validation Checklist (VCL) covering business, security, and operational controls, currently transitioning to VCL 8.0 |
| Microsoft Azure | Azure Expert MSP | Requires an underlying Solutions Partner designation (e.g., Infrastructure (Azure)) plus a separate performance and skilling audit |
| Google Cloud | Google Cloud MSP Initiative | Requires Infrastructure and Cloud Migration specializations, validated through third-party audit of customer case studies |
AWS's version of this is changing the most right now, which is why it's worth walking through in detail: AWS's Validation Checklist just moved to version 8.0, its "AI-First" release. It adds 24 net-new controls and updates 27 more, covering agentic AI platforms, Responsible AI governance, prompt injection prevention, and new operating roles like Forward Deployed Engineers, out of 61 controls total. VCL 7.1 stays valid only through the end of 2026; VCL 8.0 becomes the only accepted checklist on January 1, 2027.
The practical takeaway for anyone evaluating a cloud MSP, on any of the three platforms: ask how the provider is preparing for whatever the current or upcoming validation cycle requires, not just whether they currently hold the designation. For AWS specifically, the full breakdown of what changed under VCL 8.0, control by control, is in AWS MSP Program VCL 8.0: The Complete AI-First Gap Analysis.
DoiT holds the AWS Managed Services Provider Program Designation, awarded in December 2025 (see DoiT's AWS partner profile), and is also a validated Google Cloud partner. Across all three clouds, DoiT manages more than $8 billion in cloud spend for 4,500+ customers across 27 countries. DoiT also built PartnerOps Channel Management specifically to help other AWS partners get through the VCL 8.0 audit and stay compliant between renewal cycles. See how it maps to the new checklist for the full mechanics. For companies evaluating an MSP across any of the three major clouds, DoiT's MSPs and Distributors page covers how that support works end to end.
How Big Is the Managed Services Market?
The managed services market was valued at $401.2 billion in 2025 and is projected to grow to $437.3 billion in 2026, reaching $847.4 billion by 2033 at a 9.9% compound annual growth rate, according to Grand View Research. Growth is being driven by increasingly complex hybrid IT environments, rising cybersecurity threats, and, most recently, the operational burden of running AI and agentic workloads, which has pushed AI cost management and governance into what MSPs are now expected to cover, not just infrastructure uptime.
How Do You Choose a Managed Service Provider?
Before signing with any MSP, look for:
- Independent validation, not just self-reported expertise. On AWS, that means the AWS MSP Program Designation; on Azure, Azure Expert MSP; on Google Cloud, the Google Cloud MSP Initiative. All three require passing an audited checklist rather than a sales pitch.
- Clear scope boundaries. Confirm exactly which of the MSP/MSSP/CSP functions above the provider owns directly versus subcontracts.
- Transparent, scoped pricing. Get a quote based on your actual environment size and coverage depth, not a generic rate card.
- Hands-on engineering, not just dashboards. Ask whether the contract includes engineers who can actually implement fixes, such as Forward Deployed Engineers, versus alerting only.
- AI and cost-governance readiness. Given how fast AI workload management has become a baseline expectation (and, for AWS partners, an audited requirement under VCL 8.0), ask specifically how the provider handles AI cost attribution and governance today.
FAQ
What is a managed service provider in simple terms? A managed service provider is a company that runs and monitors another business's IT systems (networks, servers, cloud infrastructure, or security) for a recurring fee, proactively rather than only responding when something breaks.
What's the difference between an MSP and an MSSP? An MSP covers broad IT operations; an MSSP specializes specifically in security monitoring and incident response, typically through a dedicated security operations center. Many MSPs bundle MSSP-style services, but a standalone MSSP goes deeper on security alone.
Is a cloud provider like AWS itself an MSP? No. AWS offers its own first-party operations service (AWS Managed Services, or AMS), but that's distinct from third-party AWS MSPs, which are independent companies validated through AWS's MSP Program to manage a customer's environment, often across a broader scope than AMS covers. See What Are AWS Managed Services? for the full comparison.
Do Azure and Google Cloud have MSP validation programs too? Yes. Microsoft runs Azure Expert MSP, which requires an underlying Solutions Partner designation plus a separate audit, and Google Cloud runs its own MSP Initiative, which requires Infrastructure and Cloud Migration specializations validated through third-party review of customer case studies. AWS, Azure, and Google Cloud each independently audit their MSP partners rather than accepting a self-reported claim.
How much does a managed service provider cost? Pricing is typically a flat monthly retainer, a percentage of managed cloud spend, or a per-device/per-user rate. Cost depends on environment size, coverage depth (e.g., 24/7 vs. business hours), and how much security or FinOps work is included versus billed separately.
Do I still need an MSP if I use a cloud provider's own managed offering? Often, yes. A cloud provider's native managed service typically covers specific first-party operational tasks; an MSP layers in broader work that's usually out of scope, including FinOps, cross-service security operations, and hands-on engineering support.
