A Quick Tour of Azion's Edge Functions

March 31, 2021

As part of our official release of JavaScript support for Edge Functions, we’ve rounded up and summarized past blog posts on Edge Computing and Edge Functions. This primer will give readers a conceptual view of how our Edge Computing platform is set up and how Edge Functions work. In addition, it covers Edge Functions' attributes and features, discusses its key benefits, and describes the underlying technologies that help to make it great.

Why Azion Chose the V8 Engine for Edge Functions

March 30, 2021

One of the key advantages of serverless is that much of the complexity of development is abstracted away, enabling developers to focus on what matters most: crafting the best possible functionality and user experience. However, from time to time, we at Azion like to share with our readers some of the techniques we use under the hood to deliver the best possible performance, security, cost-efficiency, and resource use. Foremost among these tools is Google’s V8 Engine. The V8 Engine is embedded in our core technology, Azion Cells, and used under the hood of our new serverless computing product, Edge Functions, which is now available with JavaScript support.

History of JavaScript

March 24, 2021

The history of JavaScript is, in many ways, the history of the modern Internet. Anyone who remembers the static, clunky, and slow-loading web pages of the early Internet—or even caught a glimpse of them via the Wayback Machine—has a sense of just how much web development has evolved since the 1990s. Interactive elements such as animation, fillable forms, and even the ability to scroll through articles like this one are largely due to the rise of JavaScript—a programming language that was initially developed in 10 days and conceived as a “sidekick” to Java.

Edge Caching: Next-Generation CDN Services

March 17, 2021

From their emergence in the late 1990s, content delivery networks, or CDNs, have been instrumental in reducing Internet bottlenecks and speeding delivery by caching content close to end users. However, the Internet of today is very different from the Internet of the 1990s; as a result, today’s site and application owners need CDNs capable of providing more services, processing more requests, and quickly delivering high-resolution images, video streaming, and dynamic content to a wide variety of devices.

Edge Functions Make Cents: The Economics of Serverless Computing

March 9, 2021

Serverless computing provides a cost-effective way for companies to leverage the power of edge computing by eliminating upfront fees and outsourcing the cost of operating and maintaining servers to cloud providers. Not only does serverless computing reduce capital expenditures and maintenance costs, performing serverless workloads at the edge has significant long-term cost advantages as a result of the reduced distance data has to travel, necessitating less bandwidth and computational power than processing in cloud providers’ centralized data centers.

Signature-based vs. Scoring-based WAF

March 5, 2021

Web Application Firewalls, or WAFs, are a key component of modern web security. According to Verizon’s 2020 Data Breach Incident Report, over 80% of attacks last year targeted web applications--an unsurprising statistic given the ever-increasing size of modern applications’ attack surface. However, not all WAFs are created equal. As both cyber attacks and web applications become more and more complex, WAFs must use increasingly sophisticated techniques to secure applications--and to ensure that protection does not come at the expense of performance.

Minimize Vendor Lock-in with Edge Functions and Edge Orchestrator

March 4, 2021

The need for agile applications, on-demand scalability, high performance, and round-the-clock availability have all driven increased adoption of cloud computing, Edge Computing, and serverless architecture. Despite the benefits of these technologies, some companies are still hesitant to adopt them due to the fear of vendor lock-in. Knowing how to mitigate the risk of lock-in can help companies avoid unexpected costs and complications as they migrate to the edge and the cloud.

Why Azion is Using the Rust Programming Language

February 12, 2021

Previously in this series of posts on microservices, we discussed the features and traits necessary to next-generation applications. As 5G and Edge Computing infrastructure are built out, ultra low-latency and reliable applications and services will become increasingly common, accelerating already high user expectations for performance. In addition, with more people working, shopping, and learning online than ever, strict security measures will be needed to meet compliance requirements and ensure consumer privacy.

App Modernization: Rehost, Refactor, Rearchitect, Rebuild, and Replace

January 28, 2021

Anyone who’s ever postponed installing a new OS to the newest version can attest to the technical issues that arise when older systems are not updated. Continuing to use outmoded technology can lead to a world of problems, from security issues to poor performance and reliability. As a result, the need to modernize is clear to many businesses. However, the process for modernization is decidedly less straightforward, with strategies that run the gamut from “lifting and shifting” an application onto newer infrastructure to replacing or rewriting the old application from scratch.

Getting Your Business Ready For Microservices

January 25, 2021

Microservices were once an alternative to monolithic application architecture. They presented a new mode of development with its own set of risks and rewards. Now, we are reaching a tipping point where it’s no longer a question of whether to migrate, but when to migrate. However, migrating is a challenging process that can pose problems if executed poorly. This post will cover why microservices are necessary, the challenges of migrating to microservices, and how to devise a plan for migration.

Monolithic vs. Modern Applications

January 21, 2021

One of the buzziest topics that exists in computing today is over the modernization of legacy applications. With the rise of 5G, Edge Computing, and serverless architecture, many companies are wondering whether--and how--to rethink applications for today’s digital landscape. To help shed some light on these concerns, we’re introducing a series of posts that will discuss application modernization from a variety of business and technical perspectives, with a focus on one of the most widely discussed aspects of modernization, the use of microservices.

The Coming of Age for 5G Private Networks

January 5, 2021

This past June, 3GPP completed Release 16, which not only provided support for ultra-low latency communications (URLLC) and massive machine-type communications (mMTC), but also helped realize another Industrial IoT building block: private networks. Private networks are cellular networks used by individual enterprises or other organizations, such as police stations or fire departments, and configured for the organization’s individual needs.

Modern App Architecture for 5G Networks

December 29, 2020

It’s almost impossible to talk about 5G without using words like “game-changing,” “revolutionary,” and “breakthrough.” And while we tech bloggers tend to use these words a lot, it’s not hyperbole in this case: 5G standards really are much more ambitious than the capabilities of LTE and legacy networks. But in order to deliver on the promises of 5G networks, the devices and applications using them will need to be as efficient as possible.

Multi-Access Edge Computing: Enabler of 5G Standards

December 8, 2020

You may have heard the phrase “no latency, gigabit experience” as a shorthand for what 5G will deliver. However, 5G’s capabilities extend far beyond improving the performance you’ll get on your mobile phone. It will also populate smart cities and with high-density, low-energy consumption IoTs that can be used to improve public safety and conserve resources, and will enable mission-critical uses like remote surgery, where a high-speed, uninterrupted network connection is literally a matter of life and death.

Azion Introduces Layer 7 Load Balancer

December 7, 2020

A load balancer is similar to a reverse proxy. That means it acts as a proxy for the server in client-server connections, as opposed to a forward proxy, which would act as a proxy for the client. When a client device attempts to connect to a service, a load balancer for that service accepts the connection, and then decides which of its servers to forward the connection to, based on the rules of the load balancing algorithm it was programmed with (more on that in a moment).

Provision and orchestrate applications on Edge

November 28, 2020

At Azion, we take pride in our ability to offer high-performing, low latency serverless capabilities to businesses of all sizes. We couldn’t have done any of this without our sophisticated orchestration technology, which manages our complex infrastructure and has enabled us to automate the daily maintenance of our ICT. It’s been the backbone of our company for years, but we only recently realized that a tool this powerful should be put directly into the hands of our customers.

Impact of 5G on Digital Transformation

November 27, 2020

It’s no secret that the growing prevalence and sophistication of mobile devices has transformed everyday life. Just a few decades ago, movies could only be viewed in theaters or at home, maps were physical objects you kept in your car’s glove box, and video chatting was the stuff of science fiction. Now, anyone who can’t download Netflix, Google Maps, and Zoom on their phone is practically a Luddite. However, as wireless devices become more widespread and sophisticated, they will require additional bandwidth, quality, and network availability—which is exactly what 5G was designed to deliver.

The Current State of 5G Deployments

November 27, 2020

Fully harnessing the power of 5G, the fifth generation of mobile networks, is a bit of a chicken-and-egg situation. 5G’s game-changing performance is due to its ability to run over radio frequencies in higher parts of the spectrum than is supported by today’s 3G and 4G networks. However, it will cost billions of dollars for telcos to pay for spectrum bands and build the cell towers and antennas needed to scale 5G networks, and consumers won’t be able to use these networks until they buy devices that can connect to 5G’s sub-6 GHz and mmWave frequencies. In other words, until 5G infrastructure is widely available, consumers won’t be motivated to buy 5G devices, and until more people are using 5G devices, there’s no reason to scale 5G infrastructure.
