VPCs: An Introduction to Secure Business Networking

You’ve heard of cloud computing and how businesses use it, but do you know about virtual public clouds? VPCs are designed to give users a private cloud experience on a public cloud. For many, this is the best of both worlds when it comes to cloud storage: you get the benefits of a private cloud with the resources available on the public cloud.


Key choices in AWS network design: VPC peering vs Transit Gateway and beyond

This blog post is the first in what we intend to be a series to detail Ably’s journey in building the next iteration of our global network. It focuses on the design and we will follow up with posts detailing the building, and finally migration from old to new. If you are interested in how you can network AWS accounts together on a global scale then read on! Ably operates a global network spanning 8 AWS regions with hundreds of additional points-of-presences.


Choosing the right network architecture for your Apigee-fueled APIs

API gateways are a critical component of a modern architecture. Apigee X is Google Cloud's API management platform. It also allows users of the legacy Apigee Edge product to leverage Virtual Private Cloud (VPC) products and features, like Cloud Armor and Load Balancers. With these new security and availability advantages come a new set of challenges. The biggest challenge is accessing API backends in multiple VPCs. This introduces VPC peering transitivity restrictions.


Downstream and Upstream Mutual TLS With an API Gateway

Like many developers and operations professionals, you may have had complicated experiences with security and certificates (encryption of the connection and authentication). Maybe so much so that you try to avoid working on them whenever possible. If you’re looking for a simpler way, Kong may be the answer. As with everything with Kong, the idea is to make things as lightweight as possible, including the complexity of setting up and maintaining certificate-based security.


Apache vs NGINX: How to Choose The Right One?

Web servers are the backbone of the internet. Without web server software like Apache and NGINX, the internet might not be what it is today. However, they are no longer interchangeable. The discussion between Nginx and Apache has been going on for a long time. Both of these servers are industry giants, collectively providing more than half of all web pages on the internet.


Telecom Network Analytics: Transformation, Innovation, Automation

One of the most substantial big data workloads over the past fifteen years has been in the domain of telecom network analytics. Where does it stand today? What are its current challenges and opportunities? In a sense, there have been three phases of network analytics: the first was an appliance based monitoring phase; the second was an open-source expansion phase; and the third – that we are in right now – is a hybrid-data-cloud and governance phase. Let’s examine how we got here.


Difference Between IPv4 and IPv6: Why haven't We Entirely Moved to IPv6?

IPv4 and IPv6 are the two versions of IP. IPv4 was first released in 1983 and is currently widely used as an IP address for a variety of systems. It aids in the identification of systems in a network through the use of an address. The 32-bit address, which may store multiple addresses, is employed. Despite this, it is the most widely used internet protocol, controlling the vast bulk of internet traffic. IPv6 was created in 1994 and is referred to as the "next generation" protocol.


Why you should be using a VPN when working from home

With so many of us working from home full time for the last 16 months, VPNs have become essential tools for companies to keep their staff working in a safe environment. What we mean by “safe” is mainly about your online presence whilst performing daily tasks for your job.
