What Are the Basics of Serverless Computing, Containers, and VMs?

What Are the Basics of Serverless Computing, Containers, and VMs?

November 23, 2021

The rise of cloud computing brought on-demand computing services to users connected to the Internet. Between 2006 and 2008, computer resources, such as storage and processing capacity, began to be offered commercially for medium and large companies. The increase of its popularity only forced the original cloud computing model to transform to new approaches or paradigms for providing more virtualized resources to a broader audience. Nowadays, we have many digital devices sending large amounts of data with high speed in real-time and connected to the network for long periods. This new approach requires virtualization with high computational capacity that can be decentralized and easily scalable. Edge computing addresses these challenges by enabling new architectures.

Digital Transformation: Move to the Edge in Five Steps

Digital Transformation: Move to the Edge in Five Steps

November 11, 2021

Digital transformation has been one of the most debated terms for a while. And this debate is not in vain. Currently, any business in any industry must rely in large part on its technological infrastructure in order to stay at the forefront and compete in the market. However, not everyone knows what tools or models to choose. This often leads to maintaining legacy structures, indefinitely delaying the digital renewal process or making an investment in tools that do not meet the needs. They all mean falling behind in this very exhaustive race.

A Quick Guide to Securing Serverless Applications

A Quick Guide to Securing Serverless Applications

October 26, 2021

Since its inception, the serverless model has revolutionized computing--but how has it changed security? Serverless computing platforms enable developers to build and run applications that are managed by the serverless provider, with automatic scaling and resources charged on a per-use basis. This means that the underlying infrastructure is not only provisioned and managed, but secured by the serverless provider, so developers don’t need to worry about some of the greatest security risks, such as known vulnerabilities in unpatched servers.

The Basics of Image Processing

The Basics of Image Processing

May 28, 2021

A website without images would be unthinkable in today’s Internet. Not only are images necessary to create beautifully designed web pages, they have been found to drive conversions, social sharing, and user engagement. But the time and resources required to transfer photos, logos, artwork, and even some text to create the full composition of the web page is so intensive that images may seem less like an asset and more like a liability. That’s why image processing is crucial to the success of any digital business—and can mean the difference between whether your users find themselves looking at a crisp, colorful website versus a fragmented page of placeholders or a blank loading screen.

History of JavaScript

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

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

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.

Application Modernization - Hype or Reality? What It Really Means for You

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

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 Applications vs. Microservices

The Coming of Age for 5G Private Networks

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

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

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

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).

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

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

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.
