The Journey to Oracle Cloud: Episode 06 - What’s important to know about Latency?

We have reached our sixth stop on the The Journey to Oracle Cloud. In this episode, Rafael is meeting Petter Minge and Ommund Øvrelid to talk about network latency in the cloud.

Who is Petter and Ommund?

Petter and Ommund are two of our Oracle Cloud database specialists. They have worked as architects with Oracle for several years and are both experts on Oracle Cloud security.

What is latency?

The short description of network latency is how fast the data travels on a round trip. For example if you are entering a command in an application and are waiting for the answer to return.

We distinguish between high latency and low latency:

High latency: If the data travels slowly, you have a high latency.
Low latency: If the data travels fast, you have a low latency - we want a low latency.

Why is latency so important in the cloud?

Latency is always important to keep in mind whether it is in the cloud or on-prem, but in on-prem environments, the application and the databases are often quite close to each other.

This means that if something is triggered or sent from the application to the database, the response-time is normally very quick. The longer the distance is between the application and the database, the higher the latency can be.

A straight motorway is faster to drive than a road with a lot of traffic lights or a winding road.

In the cloud it is not so easy to place the application and the database close to each other. Whether the application is installed on-prem or at another cloud vendor and even though the waiting time is maybe only 10 milliseconds, it could have major impact on the use of an application. 

How can we build a cloud solution with acceptable low latency?

In theory, the best solution would be to have everything in one perfect cloud, where you have all the optimised technologies, services, databases and applications. But that cloud doesn't exist!

Normally, we see that Windows applications and services are optimized in Azure, while Oracle services, databases and applications are optimized in Oracle Cloud. Therefore, the best solution is normally a multi cloud solution, where you can pick and choose the best technologies from both sides.

The solution is a multi-cloud solution. In a multi-cloud solution, you can pick and choose the best  technologies from both sides. 

Oracle and Microsoft multi-cloud

In 2019, Microsoft and Oracle entered a cloud partnership, where they now provide unified identity and access management, an integrated and collaborative support model and a fast connection between their clouds (Azure and Oracle Cloud) to ensure low latency.

By using a fast connect between Oracle and Azure in the same region, it is possible to reduce the latency between the two cloud platforms to about 1-2 milliseconds - that is really fast.

SYSCO is one of few cloud experts in the Nordics that has done real live projects enabling a multi-cloud strategy using Microsoft Azure and Oracle Cloud.
