Definition of Unified Communication as a Service

Unified Communication as a Service, or UCaaS, is a cloud-delivery model that glues all the video, audio, and messaging apps into a single interface. This tool is a one-person army for businesses; it includes a range of collaboration and productivity tools packed up in one platform.

With the UCaaS system, business teams don’t have to switch seamlessly between multiple channels to pass on the message. It eliminates the need for multiple platforms or providers for different purposes. 

For instance, businesses may use multiple tools for communication; UCaaS jampacks several communication tools businesses use daily into one platform. All can be done from a single interface or platform, from messaging teammates to calling customers to virtual meetups with investors.  

Unified Communications as a Service streamlines the workflows and processes of the business. Moreover, it allows employees to stay connected from around the globe.

Unified communications solutions also eliminate the need to switch between multiple communication tools, boosting workplace organization, efficiency, and productivity.

How does UCaaS Work?

UcaaS system utilizes software that supports synchronous and asynchronous communication so employees can communicate efficiently. It is typically provided on a subscription basis by the UcaaS provider, so businesses must pay a certain amount to use its services.

The UcaaS provider creates a cloud-based platform for the business. It means furnishing everything from installing the software to customizing the settings and setting up user accounts. 

The provider sets up the platform by utilizing the business’s current setup to access all the essential tools from anywhere. 

UCaaS depends on cloud computing infrastructure, so it delivers the platform to the business via the Internet. Hence, it means that the underlying technology, software, and all the other components are hosted and operated by the chosen UcaaS provider in data centers.

UcaaS provides all the critical tools like instant messaging, file sharing, video conferencing, cloud telephony, and app integrations. Employees can access the platform from any mobile phone, laptop, or desktop device. 

  • Voice: Unified Communications as a Service deploys Voice over Internet Protocol (VoIP) to make and receive calls. VoIP or Voice Over Internet Protocol allows you to make calls in any area of the globe using an internet connection and an internet-supported device.
  • Video: It provides businesses with a cloud-based video conferencing platform. With its help, employees can organize online meetings or webinars with co-workers, customers, or supervisors, regardless of the location.
  • Messaging: Employees can get many messaging options to contact their teammates or customers. UcaaS offers features like instant messaging and chat sessions for quick communication between each other. Presence information is critical for knowing when the teammate will be online for a chat or collaboration.
  • Collaboration: The UCaaS platform offers businesses a range of collaboration tools, like file sharing, shared calendars, and real-time document editing. These tools allow employees to forward documents conveniently, communicate effectively, and collaborate on tasks.

Types of UCaaS Architectures

There are many types of UCaaS architecture, and they mainly depend on the provider and the organization’s requirements. Here are some:

1) Single-tenancy architecture

In this type of UCaaS architecture, each organization has its own set of resources. The business has a secure platform that can be integrated with the current on-premise applications.

The hardware and software offered by the chosen provider are dedicated to that customer. Most importantly, Person A’s data is kept separate from Person B’s.

Hence, this model or type of UCaaS architecture is more secure and trustworthy as each customer’s data is private and kept apart from others. But, it is also high on the price because the provider has to deploy more hardware and software.

2) Multi-tenancy architecture

Here, multiple customers have to share the same UCaaS platform. The provider’s hardware and software are distributed or shared among multiple customers, not one.

Since every customer shares the same cloud size and resources, this multi-tenancy model is relatively cheap compared to others. But on the downside, it is a low-secured kind of architecture. The reason is that multiple customers’ data is stored on the same platform.

Besides that, it is less flexible and offers few customization options.

3) Hybrid architecture

Hybrid architecture can also be referred to as combining single-tenant and multi-tenant models. In other words, it includes parts of both single-tenancy and multi-tenancy architectures

This type of architecture is also getting trendy since businesses can reap the benefits of both models from a single place. Businesses that want to shift applications to the cloud and are tight on budget can rely on this architecture. 

Some UCaaS providers offer a hybrid approach, allowing businesses cost-effectiveness and tight security.
