What is the Delivery Model of Managed Services?

September 18, 2019

These days, IT managers are under constant pressure to meet operational expectations, security requirements, and performance improvement needs - all while keeping costs down.  In order to deal with this, they are turning to managed service providers, also known as MSPs.

MSPs handle IT services with a holistic approach, which results in a much higher standard compared to what most organizations can attain in-house. Top-notch providers also give clients ongoing maintenance and management of the existing infrastructure, plus service guarantees and end-user support.

Managed Service Delivery Model

When it comes to the delivery model of managed services, it depends on the kind of service being managed or delivered. For instance, Cloud models typically include three types of delivery models:

• Platform as a service (PaaS )

• Software as a service (SaaS)

• Infrastructure as a service (IaaS)

Below are the things you need to know about each model, as well as the benefits they can bring to your business.

1. PaaS

In the PaaS software delivery model, developers rent everything they need to create a specific application. They depend on a cloud provider to give them access to operating systems, infrastructure, and development tools.

PaaS is known to make web application development simple. From the perspective of the developer, the process of all backend management happens behind the scenes. While PaaS may seem similar to serverless computing, there are lots of differences between the two.

Examples of PaaS include Magento Commerce Cloud, Force.com, Stratos, Apache Stratos, OpenShift, Windows Azure, and Heroku.

2. SaaS

SaaS is a software delivery model in which a third-party service provider is responsible for hosting applications. The provider is the one making these applications available to customers through the internet.

SaaS is considered closely related to the on-demand computing software and application service provider (ASP) software delivery models. Similar to ASP, this model involves the provider hosting the client's software, and then delivering it through the internet to approved end-users.

Examples of SaaS include Salesforce, Hubspot, Slack, MailChimp, ZenDesk, BigCommerce, DocuSign, Google Apps, and Dropbox.

3. IaaS

With the IaaS delivery model, you get services such as virtualization, networking, and pay-as-you-go storage. Users of IaaS offer users cloud-based alternatives to on-premise IT infrastructure, eliminating the need to invest a lot in costly resources for on-site operations.

Aside from its scalability and flexibility, IaaS solutions can be replaced whenever you need without losing your initial investment. Another benefit of the IaaS delivery model is it offers you control over the infrastructure. Instead of putting the responsibility on an external IT contractor, you have the ability to oversee and access IaaS platforms if you want.

Examples of IaaS include Google Compute Engine (GCE), Magento 1 Enterprise Edition, Digital Ocean, AWS EC2, and Rackspace.

Finding the right service delivery model is critical to any business because it helps you achieve a high-quality outcome within a specific budget and time frame. As a business owner or manager, you may decide to start using managed services with one type of delivery model, or even find a need for all three. Whichever option you select, remember that it should depend on the complexity and size of your enterprise.
