No matter the size of the business, the ever-growing list of IT requirements can make it difficult for an organization to manage them all on their own; particularly startups and small businesses need the capability to back up data, enterprise-level cybersecurity and continual network support.
While many organizations would rather tackle these needs in-house, the cost of internal IT can be prohibitive; both finding and maintaining talented staff can also be challenging. Therefore, businesses look to outsource IT.
As the name implies, outsourced IT is simply employing external service providers to supply IT-enabled business application services, processes and infrastructure solutions for business outcomes.
Outsourcing IT can allow organizations to lower expenses, hasten time to market, capitalize on the experience of experts, assets, and intellectual property. A few of the most frequently outsourced IT services include computer system installation/configuration/integration, tech support, remote monitoring and management, mobile device management, cloud infrastructure and voice services.
In managed hosting, service providers lease dedicated servers and the requisite hardware, such as dedicated servers, network hardware, system software and operating systems and manage those systems on behalf of the customer. The customers are referred to as tenants, and in this scenario, the leased equipment is dedicated to only a single customer, known as single-tenancy architecture.
Although the customer typically holds administrative access to their leased hardware and systems, they seldom use that access, preferring instead to interface with their systems via a web-based interface.
A DCaaS supplier provides offsite physical data center facilities and infrastructure as a service to their customers by renting or leasing access to their data center, use of their servers, networking, storage and additional computing resources. A DCaaS provider may also offer data management tools for problem/incident management and/or server and security optimization and utilization.
The typical business that would leverage a DCaaS provider is one that is no longer able to expand its own data center or a company that is unable to establish or maintain its own data center in its entirety; some reasons this may be the case include lack of capital, bandwidth, experienced IT staff, power, or any variety of other reasons.
Infrastructure as a service (IaaS) is one of the three main components of cloud computing services (the other two being software as a service (SaaS) and platform as a service (PaaS). In an IaaS model, a cloud provider hosts the infrastructure components that conventionally exist in an on-premises data center, including networking and storage hardware, servers and even the virtualization/hypervisor layer—a virtual machine monitor (VMM) that enables various virtual operating systems to run concurrently on a computer system.
Desktop as a Service (DaaS) is a form of Virtual Desktop that is managed by a service provider and allows for more control and security over end-user devices.
DaaS is offered as a subscription model, charged per user. Customers have the ability of sizing users for compute and storage, so they have the resources needed to fulfill their roles. DaaS is focused around windows-based operating systems and typically not available for Apple operating systems.
Virtualizing the end-users allows for data to be centralized, increasing security and providing more agility.
End-users can use almost any laptop or desktop, so long as it can access the internet. Meaning, if they lose or break their device, they can quickly and easily use a replacement.
It can also prove to be cost-effective because end-users no longer need high-performance devices. Other benefits include:
VDI (Virtual Desktop Infrastructure) requires a high upfront investment from the customer, whereas DaaS (Desktop as a Service) is provided as a monthly charge from a third party with no upfront costs.
DaaS also provides additional advantages including support from the third party; however, they are essentially the same, the primary difference is that DaaS is a cloud-based solution.
ITaaS is an umbrella term for outsourcing IT services for business. ITaaS can be as simple as outsourcing Tier 1 and 2 help-desk duties to an outside entity or as complex as outsourcing your routing, switching, security, wireless, and other network or cloud systems to a third party for management and maintenance.
ITaaS is targeted at businesses that lack the IT resources or internal expertise to implement, manage, and/or maintain their IT deployments
A virtual CIO is a consulting engagement in which an organization’s chief information officer (CIO) is provided by a third party to consult on the organization's IT goals, budget, applications, and overall strategy. They fill the role of the traditional CIO for all intents and purposes.
