Top 5 Cloud Networking Trends in 2022

When you think about it, the cloud is really about networking. A large repository of data or computing power exists in some nebulous or other place. To be useful, it must quickly provide data or processing resources. Otherwise, why bother? Nobody would pay for the cloud if it turned out to be much slower than if the same services were available internally.

Here are some of the top cloud networking trends for 2022:

The Grand Challenge of Cloud Networking

Enterprises today are evaluating how to develop applications that take advantage of IoT, mobile connectivity, and artificial intelligence (AI) at scale. According to most surveys, they plan to roll out such apps within the next five years. But at the same time, they admit that if they could demonstrate their ability to deliver more products at lower cost with greater reliability, they would develop and deploy such applications much sooner. Cloud networking performance gets in the way.

“While the decision to implement a proof-of-concept or lightweight mobile application on the public cloud may be straightforward, more mission-critical, mission-critical, and data-intensive applications will likely require hybrid multi-cloud deployments,” said Mike Mulica. , CEO of Alef.

“It’s not about one or two cloud deployments; there are more mid-to-high single-digit private and public clouds, making cloud (inter)connectivity performance paramount.

Intent-Based Networking

There are a growing number of applications where architecture, cloud, and infrastructure decisions become critical at the application design stage. Connectivity must be there for the application to succeed due to the complexity of multi-cloud interactions.

“Such connectivity must address critical design considerations and this is where intent-based networking becomes important,” Alef said.

Intent-based networking specifies connections and characteristics without knowing exactly how that connection is made. It is a software-enabled automation process that uses high levels of intelligence, analysis, and orchestration to improve network operations and availability. Cloud networking must incorporate intent-based networking if it is to meet the challenge.

Deterministic networking

Besides intent-based networking, the challenges of modern cloud architectures demand another change from traditional networking. Known as deterministic networking, it encompasses the implementation of deterministic data paths for real-time applications with extremely low data loss rates, packet delay variation (jitter), and limited latency. .

Intent-based and deterministic networking is essential for enterprises to accelerate the development and implementation of industrial automation applications,” said Alef.

internet security

As the network expands, clouds become more complex, and networking becomes more mission-critical, security becomes more important. A big trend, therefore, is that network managers are being forced out of their rigidly defined box to encompass a wider range of tasks, especially network security.

They may protest that they are in the business of networking, not security. But just as many other areas of computing have converged, the worlds of networking and security have become inextricably linked. Today’s network specialists only need a cursory knowledge of security protocols and best practices. They need to be able to set up secure networks, rather than waiting for security specialists to clean up their messes after the fact.

This trend is easy to see when you study networking courses today compared to ten years ago. The amount of security data now dwarfs what network specialists were once required to know.

SASE fills the void

There are, of course, many security technologies that are intimately tied to networking. Intrusion prevention/detection systems, Secure Web Gateway (SWG), Cloud Access Security Broker (CASB), Zero Trust Network Architecture (ZTNA), and Firewall-as-a-Service (FWaaS) technologies are just a few examples. But having so many separate tools to monitor network security can play into the bad guys’ hands. If these tools do not interact and allow for integrated management and monitoring, alerts may be missed. The consequences can be horrific.

According to Dell’Oro Group, Security Services Edge (SSE) fills the void by providing a way to manage these disparate tools centrally and efficiently. The SSE market grew 40% year-over-year to reach sales of $800 million in the first quarter of 2022. SSE encompasses a large number of security and networking elements, including SWG, CASB , ZTNA, FWaaS, etc.

“We identified SSE as an initial basket of four cloud-delivered security technologies that underpin security in SASE,” said Mauricio Sanchez, research director, network security and SASE & SD-WAN at Dell’Oro Group. .

“In the era of distributed applications and hybrid working, enterprises increasingly prefer cloud-delivered security over traditional on-premises solutions.”
