Search for “AWS managed services” and you get two different things mixed together. One is AWS Managed Services, or AMS, a specific offering from Amazon that operates AWS infrastructure for large companies. The other is the broad category of outside teams that run your AWS environment for you: managed service providers, DevOps consultancies and, more recently, DevOps subscriptions. If you are a CTO or founder at a SaaS company deciding who should own your infrastructure, the difference matters, because the two cover different parts of the job.

A third use of the phrase shows up when people look for an AWS managed services list. AWS describes many of its own products as managed, such as Amazon RDS, its fully managed relational database service, where AWS runs the database servers for you. That meaning is about individual services rather than about who operates your environment, so this post sets it aside.

This post separates them, walks through the five realistic options, and shows where a subscription fits and where it does not.

What AWS Managed Services (AMS) actually is

AMS is Amazon’s own operations service. AWS describes it as an enterprise service that provides ongoing management of your AWS infrastructure: monitoring, incident management, patching, security controls and backup, run by AWS operations staff around the clock.

There have historically been two operations plans:

AMS Accelerate operates your existing AWS accounts. It provides monitoring, incident management, security monitoring and backup, with patching as an add-on for EC2 workloads.
AMS Advanced added a managed landing zone, a change management system where most changes go through a request for change, access management and endpoint security.

Two details matter for a SaaS team evaluating it today.

First, AMS Advanced is being retired. AWS stopped accepting new Advanced customers on June 30, 2026, and will end support entirely on June 30, 2027. AWS points existing customers to AMS Accelerate, to its Unified Operations support plan, to AWS partners, or to running it themselves with native tools. If you are starting fresh, Accelerate is the AMS option still on the table.

Second, AMS manages infrastructure, not your software. The AMS FAQ says it plainly: “AMS does not operate or configure your applications.” Your CI/CD pipelines, your deploy process, your Terraform, the Dockerfile that broke last Tuesday, and the question of why checkout got slow after the evening release all stay with you. AWS positions it for enterprises adopting cloud at scale.

So AMS answers the question “who keeps the AWS layer healthy and patched?” It does not answer “who does our DevOps work?”

AWS managed services pricing

AMS is pay as you go. Per the FAQ, the price is calculated from the number of instances and the usage fees of the other AWS services in the accounts AMS manages, and detailed quotes come from the AWS sales team. There is no public flat rate to compare against, so budget for a sales conversation before you can put AMS next to other options.

What people mean by managed DevOps

Managed DevOps, sometimes sold as DevOps as a service, is the second meaning. An outside team takes responsibility for the work between your code and your customers: pipelines, infrastructure as code, environments, monitoring and alerting, on-call, cost control, security hygiene and the steady stream of small requests a product team generates.

The difference from AMS is scope. A managed DevOps provider works on your application’s delivery path, not only the AWS resources underneath it. When a deploy fails at 6pm, a managed DevOps team fixes the pipeline. When your largest customer asks for a SOC 2 report, they help build the controls. AMS would do neither.

The five options, compared

Most SaaS teams on AWS end up choosing among five arrangements. Here is how they divide the work.

Option	What you get	Covers app delivery?	Best fit
In-house DevOps hire	One or more engineers on your payroll	Yes	Large, steady workload; you can hire and retain
DevOps consultancy	A scoped project with a defined end	Yes, for the project	A migration, a rebuild, a one-time audit
Managed service provider (MSP)	Ongoing infrastructure operations, often with a ticket queue	Varies by contract	Many accounts, steady state, enterprise procurement
AWS Managed Services (AMS)	AWS-run monitoring, incidents, patching, backup	No	Enterprises with large AWS estates
DevOps subscription	Ongoing requests plus monitoring for a flat monthly fee	Yes	SaaS teams without a full DevOps function

Hiring in-house

A full-time DevOps engineer knows your system deeply and is in the room for every decision. The costs are the obvious one, salary and benefits, and the less obvious ones: months to find the right senior person, one person carrying the pager, and a hard dependency on someone who can resign. A team running ECS with one DevOps engineer on call has a single point of failure in the role meant to remove them. In-house makes sense once you have enough steady work for two or three people and the budget to keep them. Our post on when to hire a full-time DevOps team goes into the signals.

A DevOps consultancy

Consultancies are good at projects with a clear finish line: move from EC2 to EKS, rebuild the pipeline, get ready for an audit. You pay for the project, they deliver it, they leave. The gap appears after handover. Nobody is watching the new cluster at 3am, and the next twenty small requests have to be scoped, quoted and scheduled one by one.

A managed service provider, including AWS managed services partners

MSPs run infrastructure on an ongoing basis. AWS also has an MSP Partner Program that validates partners through a third-party audit, which is a useful signal if you go this route. AWS also works with partners inside AMS engagements: the FAQ notes that AWS partners usually cover the areas AMS does not, such as migration consulting and application management. Contracts vary widely. Some MSPs do real DevOps work; many focus on keeping servers up, patched and backed up, with application changes handled as billable tickets. Read the scope carefully: “managed” can mean anything from full ownership to a monitoring dashboard and an escalation email.

AMS

Covered above. Strong for its scope, built for enterprises, and it leaves your delivery pipeline and application operations with your team.

A DevOps subscription

A subscription combines the ongoing coverage of an MSP with the hands-on scope of a consultancy, for a fixed monthly price. You send requests as they come up, the provider works through them, and monitoring and incident response run in the background. It suits a SaaS team that has real DevOps work every week but not enough to justify a full team, or that wants senior coverage without betting on one hire.

What a subscription replaces

It helps to be concrete about which jobs move off your plate.

The pager. Somebody has to be reachable when production degrades at night. Without a DevOps function, that is usually the CTO or the most senior backend engineer. A subscription with 24/7 monitoring and incident response takes that rotation.

The backlog of small infrastructure tasks. Rotate a certificate, add a staging environment, fix a flaky GitHub Actions workflow, tighten an IAM policy, add an alert for a new service. Each is an hour or a day. Together they quietly consume a developer’s week, or they never get done.

The once-a-quarter project. Disaster recovery setup, a database upgrade, a move to containers. With a subscription these go into the same request queue instead of needing a new contract.

The cost review nobody owns. Idle instances, oversized databases and forgotten snapshots pile up when no one is assigned to look. Ongoing FinOps attention is part of the work.

The compliance scramble. When an enterprise deal requires SOC 2, someone has to build and evidence the controls. That work lands on whoever owns infrastructure.

What a subscription does not replace: your product engineers, your architecture decisions (you still make the calls; the provider advises and implements), and for very large estates, possibly an internal platform team. If you run dozens of accounts with a mature platform group, a subscription might supplement them rather than replace anyone.

How to choose

A few questions settle most cases:

Is the work a project or a stream? If it ends, hire a consultancy. If it keeps coming, you need ongoing coverage.
Do you need your application delivery managed, or only the AWS layer? If it is only the AWS layer and you are an enterprise, AMS or an MSP may be enough. If pipelines and deploys are the pain, they are not.
Who carries the pager today? If the answer is “the CTO,” that is the most expensive on-call rotation in the company.
Can you hire and keep two senior DevOps engineers? If yes and the workload justifies it, in-house is a strong choice. If not, one hire is a single point of failure.
Who owns the code? Whatever you choose, make sure infrastructure as code, pipelines and runbooks live in your repositories and stay yours if the relationship ends.

Frequently asked questions

What are AWS managed services?

The phrase has two common meanings. AWS Managed Services (AMS) is Amazon’s own enterprise service that monitors, patches, backs up and handles incidents for your AWS infrastructure, but does not operate your applications. More broadly, it means any outside team that runs your AWS environment for you, from MSPs to DevOps subscriptions.

Who are the managed service providers for AWS?

AWS itself offers AMS, and a large ecosystem of partners sells managed services on AWS. The AWS MSP Partner Program validates partners through a third-party audit, which is a reasonable first filter. Scope still varies a lot between providers, so check whether a contract covers application delivery or only the infrastructure.

What are managed services in the cloud?

Cloud managed services are arrangements where someone other than your own team takes responsibility for running part of your cloud environment. That can be a provider running whole accounts, like AMS or an MSP, or a cloud product that hides the servers, like a managed database. The question to ask is always which part of the work moves off your team.

What are examples of managed services?

On AWS, examples include AMS Accelerate for infrastructure operations, MSP contracts for ongoing operations, and managed DevOps or DevOps subscriptions that also cover pipelines, deploys and on-call. At the product level, Amazon RDS is an example of a fully managed AWS service.

How Webera does managed DevOps on AWS

Webera is a DevOps subscription for SaaS teams on AWS. Senior engineers work alongside nine AI agents, each with one job: Sentinel for observability, Guardian for security, Conductor for CI/CD, Dispatcher for incidents, Optimizer for FinOps, Navigator for networking, Keeper for databases, Forge for application readiness and Warden for standards. The agents do the watching, routing and first analysis around the clock. The engineers make the calls and ship the fixes.

There are three plans, priced by the month:

Pro, $4,999 a month. Unlimited requests with two active at a time, 24/7 monitoring and incident response, and an average 36-hour turnaround. You can start Pro online.
Elite, $9,999 a month. Three active requests, a named engineer and a customer success manager, a compliance concierge for SOC 2, HIPAA and PCI, and an average 24-hour turnaround.
Platform, $14,999 a month. A team working inside your sprints, with multi-account and Kubernetes operations and knowledge transfer to your engineers.

Every plan has a three-month minimum, billed monthly, then continues month to month. You own all the code and configuration, and everything is documented so it can be handed over.

If your team is weighing a hire, a consultancy or AMS, compare the plans on our pricing page and see whether a subscription covers the work you have.
