Understanding the Different Types of Cloud Infrastructure: Traditional, Hyperconverged, and Distributed

Cloud computing has become an essential component of modern businesses, providing a flexible and scalable way to store and access data. There are different types of cloud infrastructure, including traditional, hyperconverged infrastructure (HCI), and distributed cloud architectures, each with its unique benefits. To make an informed decision, it’s vital to understand the differences between them. In this article, we will explore the three cloud infrastructure types, their advantages, and disadvantages.

Organizations can harness the power of cloud computing by choosing the right infrastructure type that matches their business needs. Traditionally, businesses used the on-premise infrastructure model, where they owned servers and other IT equipment and operated it in-house. However, this infrastructure model came with high maintenance costs, including hardware, software, and personnel, and lacked scalability and flexibility. Cloud computing emerged to address these challenges by providing a pay-as-you-go model where businesses only consume the resources they need, when they need them.

Understanding the Three Types of Cloud Infrastructures

There are three types of cloud infrastructure: traditional, hyperconverged infrastructure (HCI), and distributed cloud architectures. Traditional cloud infrastructure refers to the classic public or private cloud model, where the computing resources, networking, and storage are in one location.

Hyperconverged infrastructure (HCI) simplifies the traditional cloud model by consolidating all the compute, storage, and networking resources into a single appliance. Distributed cloud architectures work by distributing resources closer to end-users and enabling dynamic resource allocation. All types of cloud infrastructure are designed to allow businesses to leverage the idea of pooling resources that can be drawn upon as needed.

The main differences between traditional, hyperconverged, and distributed cloud infrastructures

Pavel Despot, Senior Product Manager at Akamai, explains that the main differences between traditional, hyperconverged, and distributed cloud architectures come down to location. Traditional cloud infrastructure is centralized and located in one place, whereas hyperconverged infrastructure is consolidated into a single appliance. Distributed cloud architectures, on the other hand, utilize distributed resources much closer to the end-users.

How do hyperconverged solutions allocate resources for computing, storage, and networking functions?

Hyperconverged solutions use commonly available hypervisors to allocate resources for various compute, storage, and networking functions. Hyperconverged solutions are beneficial because they offer simple scaling, ease of management and deployment, as well as cost-effective scaling.

The differences in scalability and flexibility between hyperconverged, traditional, and distributed cloud infrastructures

Cory Peters, Vice President of Cloud Services at SHI International, explains that the crucial difference between hyperconverged, traditional, and distributed cloud infrastructures is their scalability and flexibility.

Traditional cloud infrastructures provide good scalability for businesses since they rely on resource pooling. However, scaling up may involve adding more servers in the data centers or cloud regions. On the other hand, the scalability of hyperconverged solutions is limited to the capacity of the appliance. This limits organizations’ ability to scale beyond the appliance’s capacity.

Distributed cloud infrastructure provides scalability and flexibility benefits, particularly in edge computing scenarios. This infrastructure type distributes resources closer to end-users, improving response times, enabling dynamic resource allocation, and reducing latency issues.

The caution from Swaminathan Chandrasekaran on cost management for distributed cloud infrastructure

Swaminathan Chandrasekaran, Principal and Global Cloud CoE Lead at KPMG, warns that distributed cloud infrastructure can raise costs if not properly managed. The dynamic resource allocation and distribution require careful monitoring to ensure that businesses consume only the resources they need and minimize waste.

The Cost Perspective of Shifting from a CapEx Model to an OpEx Model in Traditional Infrastructure Compared to Public Cloud

The biggest cost difference between traditional infrastructure in your data center and moving to the public cloud is shifting from a capital expenditure (CapEx) model, where you own your own infrastructure assets, to an operational expenditure (OpEx) model, where you pay for what you use. This shift allows businesses to optimize their IT infrastructure costs by eliminating the overhead costs associated with owning and maintaining IT infrastructure on-premises.

Choosing the right type of cloud infrastructure is a crucial decision for businesses looking to shift to cloud computing. While traditional cloud infrastructure is cost-effective and provides good scalability, it may not be suitable for organizations requiring fast response times. Hyperconverged infrastructure offers good scalability and ease of management, but it has limited capacity for scalability. In contrast, distributed cloud infrastructure offers scalability and flexibility benefits by enabling dynamic resource allocation and reducing latency issues. Ultimately, businesses need to consider their unique needs and choose the infrastructure that best meets their requirements for agility, performance, and cost-effectiveness.
