What’s the first thing that comes to mind when you read MaaS? Maybe a heavy metal band or a video game? Well, MaaS is not just a cool name. It is super useful! Imagine you have a dream configuration and nobody can provide it. MaaS can! MaaS is literally just hardware as a service, Metal as a Service.
MaaS has become a transformative solution for managing physical servers with the flexibility you usually find in virtual machines. By streamlining the traditionally complex task of handling large-scale physical infrastructure, MaaS offers a compelling choice for cloud providers, data centers, and enterprises seeking efficient hardware management. Are you interested now?
What is MaaS?
Metal as a Service (MaaS) is a cloud-like framework that automates the management of physical (bare-metal) servers. MaaS allows organizations to deploy and manage physical hardware with the same scalability, efficiency, and agility that virtual machines (VMs) do allow. It is open-source software, useful for provisioning servers quickly with Linux, Windows, or VMware ESXi. Canonical supports and recommends it as a physical provisioning system that works with any system configuration.
Instead of managing servers one by one, MaaS allows you to turn bare metal into a flexible cloud-like solution. MaaS creates a pool out of all the physical machines you have so that you can manage them like a single unit. You can provision automatically all the incorporated machines and use them. Then, when the machines are not needed, they are returned to the pool for future use.
MaaS combines all the tools you need into a unified and streamlined system, for instance:
- Web UI.
- High availability.
- IP address management (IPAM).
- Full CLI and API support.
- Role-based access control (RBAC).
- DHCP relay integration.
- DHCP and DNS for other devices on the network.
- Inventory of components.
- Composable hardware support.
- VLAN and fabric support.
- Hardware testing.
- NTP for the complete infrastructure.
MaaS simplifies the entire lifecycle of physical server management—provisioning, configuring, monitoring, and decommissioning—through automation, making it as easy to handle as virtual resources. It is especially interesting for large-scale infrastructures, data centers, and enterprises that need direct control over hardware performance without the virtualization costs.
What are the key components of MaaS?
Тhese are the MaaS components you must know:
- MaaS controller. It is the service’s core, responsible for managing, monitoring, and provisioning the physical servers. It provides the interface (web or API) to manage nodes and resources.
- Node/servers. These are the physical machines (bare-metal servers) managed by MaaS. Nodes are registered in the MaaS controller and are ready to be provisioned or deployed.
- DHCP, DNS, and PXE boot. MaaS uses DHCP (Dynamic Host Configuration Protocol) and DNS (Domain Name System) to manage networking. PXE (Preboot Execution Environment) allows servers to boot from the network to receive their OS image.
- Operating system (OS) images. MaaS allows you to deploy various operating systems (Linux, Windows, etc.) on the physical servers, automating installation via pre-configured OS images.
- API and web interface. MaaS provides a graphical user interface (GUI) for easy interaction and APIs for integrating with other tools and systems, allowing fully automated, programmatic infrastructure control.
- Storage and networking management. MaaS automates network configurations, IP address management, and storage settings like RAID, making hardware deployment seamless.
How does MaaS work?
MaaS is a manager of nodes. MaaS transforms a pool of physical servers into an easily manageable and scalable infrastructure. After the user registers, the new system joins the pool and gets ready. The control mechanism is IPMI or Cisco UCS.
A MaaS node is not like a virtual machine in the cloud. The user has a lot more control – root access for specific adjustments and drivers’ management. Full control is the difference between the MaaS and a cloud option.
It is scalable and easy to set up. You can have a few servers or hundreds in just minutes.
Technically speaking, here’s how MaaS typically operates:
- Discovery. First of all, MaaS automatically detects and lists all available physical machines within the network.
- Commissioning. Now, MaaS tests and configures all the physical machines found in the first step, ensuring they are ready for deployment. It includes updating firmware, configuring BIOS settings, and setting up network interfaces.
- Provisioning. Once you or another user requests a machine, MaaS allocates a physical server, provisions it with the desired operating system, and then, configures it for the intended workload.
- Deployment. MaaS installs the required software and customizes configurations based on your requirements (OS, applications, network settings, etc.).
- Monitoring and management. Once deployed, MaaS continuously monitors the physical servers, checking for performance, health, and network status.
- Decommissioning. Once the server’s life cycle ends, MaaS securely wipes the hardware and prepares it for redeployment, ensuring no data remains from the previous user.
Why would you like just the bare Metal as a Service (MaaS)?
Yes, you could rent a cloud server, but it will have a pre-installed operating system. If you have a startup company, you might have very different needs from what that server can provide. You could have a specific plan, a particular OS in mind, and some specific extra software like ERP. With MaaS, you can choose exactly what you want to install. No more, no less! Ubuntu, Debian, FreeBSD, Windows, or another OS. You decide!
You can get better efficiency with the best software configuration. To give you a reference, you can get approximately a 5% increase in performance, thanks to the configuration you decided.
Benefits of MaaS
Let’s explore more the MaaS benefits for you to have a clearer picture.
- Automation. Using MaaS you can automate complex processes such as hardware provisioning, OS installation, and system configuration, saving time and reducing manual errors.
- Cost efficiency. It reduces the cost of managing hardware manually, particularly for data centers with thousands of servers. It can be a relief for your budget!
- Fast and easy installation. You can install a complete OS in only a few minutes with a simple copy-and-paste process. There is no need to format drives, create different partitions, and set up applications!
- Hardware efficiency. MaaS allows the full utilization of physical hardware, with no overhead from virtualization, offering better performance for high-demand applications.
- More processing power. It is possible thanks to the fact that no hypervisor is needed. You can access the full potential of the hardware.
- Flexibility. MaaS supports multiple OSs and configurations, making it adaptable to plenty of use cases.
- Scalability. MaaS is designed for large-scale operations, making it suitable for hyperscale data centers, cloud service providers, or large enterprises.
- No sharing. You don’t share resources with other users. Your hardware is yours and you can use it at 100%.
- Security. For companies with very sensitive data, this could be a good option. It is a super good and safe container if set up the right way.
Cons of MaaS
- Less portability. You have physical servers and they lack the portability of virtual machines (VMs), which can easily be migrated or replicated.
- Physical limitations. Unlike VMs, physical hardware cannot be resized or migrated easily between machines, which can limit flexibility.
- Higher upfront costs. MaaS reduces expenses, but requires investment in physical servers, storage, and networking equipment, making it more expensive initially than cloud-based virtual solutions.
- Complexity. If you are more used to managing and maintaining virtualized environments, executing those tasks with physical hardware can be more complex, especially in terms of scaling and disaster recovery.
MaaS vs. IaaS. Are they the same thing?
Nowadays, there are many concepts related to cloud computing (SaaS, PaaS, and IaaS). It can be confusing, but to answer the question, no, MaaS and IaaS are different concepts. IaaS stands for Infrastructure as a Service. We prepared a detailed comparison to spot easily the differences between these concepts.
| Feature | MaaS (Metal as a Service) | IaaS (Infrastructure as a Service) |
| Definition | MaaS provides automation for physical server management, offering direct access to hardware. | IaaS provides virtualized computing resources over the internet, abstracting physical hardware. |
| Deployment | Deploys and manages bare-metal servers (physical hardware). | Manages virtual machines on top of physical hardware managed by the service provider. |
| Scalability | Scalable, but limited by the availability of physical hardware. | Highly scalable, since virtual resources can be provisioned on demand. |
| Performance | High performance due to direct access to physical servers without virtualization overhead. | Slightly lower performance due to the overhead of running on virtualized resources. |
| Use case | Ideal for workloads requiring high-performance computing, databases, or specific hardware configurations (e.g., GPUs). | Suitable for a wide range of general workloads like websites, applications, and development environments. |
| Flexibility | Less flexible in terms of scaling and resource reallocation, as physical servers cannot be resized on demand. | Very flexible, allowing users to easily scale up or down, and allocate resources dynamically. |
| Management complexity | More complex since it involves physical server management (hardware failures, replacements, etc.). | Simplified management since the cloud provider manages the underlying physical hardware. |
| Portability | Limited portability; physical servers cannot be easily moved or duplicated. | Highly portable; VMs can be quickly migrated between different data centers or providers. |
| Cost | Higher upfront costs due to the need for physical hardware and maintenance. | Pay-as-you-go model, allowing for more predictable and often lower operating costs. |
| Security | Higher security, as users have dedicated hardware that isn’t shared with other clients. | Lower security than MaaS, as virtual environments are typically multi-tenant (shared hardware). |
| Ideal for | Data centers, cloud providers, and enterprises with high-performance or specialized hardware needs. | Startups, SMBs, and companies looking for fast, scalable, and affordable virtual infrastructure. |
Now, it is clearer! MaaS and IaaS belong to the world of IT infrastructure, but they serve distinct purposes. In general, MaaS provides bare-metal control and physical server management at scale. On the other hand, the benefits offered by IaaSworkthrough virtualized resources. Choosing between MaaS and IaaS depends on your specific workload requirements, performance needs, and budget. If you need full control over hardware and high-performance computing, MaaS is the right choice. However, if you prioritize scalability, ease of management, and lower costs, IaaS might be the solution for you.
Ok, so you rented the parts, now what?
MaaS has a user interface that allows you to install any OS from an ISO file. It is fast to set up and you would be ready to go.
