Infrastructure Monitoring — Best Practices, Must-Have Features, and Use Cases

Aggregated on: 2022-10-31 19:58:36

In 2017, Amazon faced an unfortunate four-hour outage, causing S&P 500 companies to lose $150 million. What was the cause? An erroneous command removed more servers than intended, causing system downtime. Although downtime is not an alien topic for developers, its impact can be deeply felt. Gartner estimates the average cost of downtime to be as high as $5600 per minute, which may build up to over $300k per hour. These are definitely scary numbers for any organization. But there’s no need to panic just yet!

However, there can be an overwhelming variety of options, each with advantages and disadvantages. You can use this article to choose a JavaScript data visualization library and learn more about its features. Here are the most important factors to consider while choosing the right JavaScript data visualization library for your project.

How To Convert Image Files Into GIF or WebP Format Using Java

Aggregated on: 2022-10-31 18:58:36

If we’re preparing to reformat an image for a specific purpose online, the new format we choose needs to accurately reflect the use case we envision. Otherwise, we’ll inadvertently stifle our own efficiency and, most importantly, run the risk of slowing down our web page loading speeds. The same can be said for most file format selections: we wouldn't use Microsoft Word to create a spreadsheet, and we wouldn't use Excel to write an essay (even though both technically can be done). Choosing which image format to use requires us to think about the exact purpose we expect that file to serve. While the most ubiquitous formats we encounter online – namely JPG and PNG – provide well-known benefits for their respective use cases, they also come up short in certain key areas. For example, while the JPG format is widely used on website pages due to its high degree of compression (allowing web pages to run faster), this degree of compression sacrifices a meaningful amount of image quality, which we may not always be willing to lose. While PNG is a lossless format with built-in transparency features – perfect for displaying things like graphs, logos, and illustrations on a solid background – it notably lacks the ability to fit common online use cases such as image animation when the need arises.

Zero Party Data — Collection, Definition, Examples and Tactics

Aggregated on: 2022-10-31 18:58:36

More often, claims like “data are the new oil” or “data is the new electricity” appear in board meetings, research articles, and presentations, highlighting the data’s power and potential worldwide. However, with such global attention to data developments, one type of data has been largely overlooked - zero-party data. What Is Zero-Party Data and Why Is It Important? The term “zero-party” data was first introduced by Forrester Research in 2022, defining this type of data as data that customers intentionally and proactively share with a brand. Zero-party data can include purchase intentions, preference center data, personal contexts, and how an individual wants to be recognized by a brand. With GDPR, CASL, and CCPA guidelines, along with Google phasing out the third-party cookies support by 2023, companies across the globe are having a hard time collecting data as these regulations directly impact their ability to run effective marketing campaigns and serve customized content. These data laws make it difficult for companies to understand customers and their brand aspirations.

How to Use ngTemplateOutlet in Angular With Example

Aggregated on: 2022-10-31 16:43:36

In Angular, we use the ngTemplateOutlet directive to insert an external template into our component's view. This powerful feature allows us to reuse templates and keep our code DRY. The ngTemplateOutlet directive takes a template reference as its input. This template reference can be a local variable declared in our component's template or a reference to an external template.

What Is Service-Oriented Architecture? Service Oriented Architecture (SOA) involves splitting different parts of your application into services. That way, you can have services for Authentication, Batch-Processing, Managing Videos, Notifications, etc. Separating core functionalities into services help your platform to scale appropriately. You also get to enjoy the benefit of the whole system not breaking down when one service malfunctions. In addition, you can improve each service without tampering with others.

Are We There Yet? When Do We Move to GraalVM?

Aggregated on: 2022-10-31 02:58:36

This is the perfect time to raise this point — just as Spring Native is coming to the forefront. Is it time to move to GraalVM? Spoiler: it depends. Yes, if you’re building serverless, probably no if you’re building pretty much anything else — with a few exceptions for some microservices. Before I begin, I want to qualify that I’m talking about native image (SubstrateVM) which is what most people mean when they say GraalVM. That specific feature took over a much larger and more ambitious project that includes some amazing capabilities such as polyglot programming. GraalVM native images let us compile our Java projects to native code. It performs analysis and removes unnecessary stuff, it can reduce the size and startup time of a binary significantly. I’ve seen 10-20x improvement to startup time, that’s a lot. Ram usage is also much lower sometimes by a similar scale but usually not as significant.

When Is It Time to Stop Using Scrum?

Aggregated on: 2022-10-31 02:28:36

TL; DR: When Should a Team Stop Using Scrum? When is the time to look beyond Scrum? After all, many things—ideas, practices, mantras, etc.—outlive their utility sooner or later; why would Scrum be an exception? Moreover, we are not getting paid to practice Scrum but solve our customers’ problems within the given constraints while contributing to the sustainability of our organization. Scrum is a tool, a helpful practice but neither a religion nor a philosophy. Which brings us back to the original question: Is there a moment when a Scrum team should stop using Scrum? Setting the Context of Using Scrum To Your Benefit When I ask whether there is a moment when a Scrum team should stop using Scrum, I am not referring to a situation in which using Scrum is useless, to begin with. For example, if you look at the Stacey Matrix below, you will notice areas colored in red—Simple and Chaotic:

Cloud Key Management Services Use Cases

Aggregated on: 2022-10-28 19:28:35

Today, the cloud environment has been chosen by many business solutions as the major hosting environment for their applications. They can either choose Software-as-a-service (SaaS), Platform-as-a-service (PaaS), or Infrastructure-as-a-service (IaaS) different solution types to build up solutions to meet business requirements. However, storing business data in the Cloud environment will have a great challenge in exposing business data to the public. As the concerns data security issues, every Cloud platform vendor provides a different solution for data security. Understanding the similarity and differences in those solutions will help the business clients choose the proper solution for the business applications. This article will discuss the primary solution use cases and major differences in secret key management among the Microsoft Azure, Amazon AWS, and Google Cloud Platform for managing secret keys, certificates, and data encryptions. Although a platform could provide a similar solution or indirect solution for a specific use case, it will still be compared as a difference as long as it is not a commonly used use case.

Best Books to Learn HTML and HTML5 in 2023

Aggregated on: 2022-10-28 17:43:34

When constructing a building of any size, paying close attention to the type of foundation the structure calls for is the most important thing you can do. If you have a solid foundation, subsequent layers built on top of it will be effectively implemented, and you won't have to worry about the third voice of doubt keeping you up at night. The same is true when it comes to producing a masterpiece of art. A painting that is skillfully painted but not on canvas of sufficient quality will not survive the test of time because of the fabric it is painted on. After completing that quick task, let's go back to the job at hand, which is finishing off this brief post about the books that are the best for studying HTML and HTML5. All web developers are aware that, much like a building or a painting, the web could not be able to flower and thrive if the very foundation of its magnificence could not resist the fury of time and development. This is something that all web developers are aware of. Time has washed away a lot of technological frameworks, tools, and languages. Still, hypertext markup language (HTML) has remained the foundation of all the web miracles we see today. HTML is the foundation of every online page, which is reason enough to treat the language respectfully.

Avoiding the Kubernetes Cost Trap!

Aggregated on: 2022-10-27 21:43:34

Kubernetes has engulfed the Developer community with its popularity. It’s still a wonder offered on a silver platter (as it is open-source). The increasing Kubernetes costs come as no surprise when it has set the de facto standard of container orchestration. Yet, here we are talking about putting curbs on our Kubernetes bills. There’s a key differentiator to think through these costs – is it spending or wasting resources? If we’re expanding our infrastructure, it’s obvious that there will be a rise in Kubernetes costs. However, while our plans to expand validate the prices, they don’t guarantee efficient usage of resources.

Putting Identity at the Center of Zero Trust

How Does Synchronization With Asyncio Look Like

Aggregated on: 2022-10-27 16:43:34

The most general view of program development approaches claims we have two basic coding options. The first one, synchronous code architecture, works step-by-step, and all the processes run the same way. For instance, each process performs data input and receives output from the server. Consequently, if we have operation one and process two, as well as input/output one and input/output two, input two starts only after output one. In asynchronous code, the architecture is not that strict and hierarchic. Our example with two operations looks different, as both operations can be performed simultaneously and remain independent. It is also called concurrent code.

Why Kubernetes Is the Best Technology for Running a Cloud-Native Database

Aggregated on: 2022-10-26 00:58:33

We’ve been talking about migrating workloads to the cloud for a long time, but a look at the application portfolios of many IT organizations demonstrates that there’s still a lot of work to be done. In many cases, challenges with persisting and moving data in clouds continue to be the key limiting factor slowing cloud adoption, despite the fact that databases in the cloud have been available for years. For this reason, there has been a surge of recent interest in data infrastructure that is designed to take maximum advantage of the benefits that cloud computing provides. A cloud-native database achieves the goals of scalability, elasticity, resiliency, observability, and automation; the K8ssandra project is a great example. It packages Apache Cassandra and supporting tools into a production-ready Kubernetes deployment.

Why Do Arrays Have To Be Deleted via Delete[] in C++

Aggregated on: 2022-10-25 22:43:33

This note is for C++ beginner programmers who are wondering why everyone keeps telling them to use delete[] for arrays. But, instead of a clear explanation, senior developers just keep hiding behind the magical "undefined behaviour" term. A tiny bit of code, a few pictures and a glimpse into the nuts and bolts of the compilers – if interested, you're welcome to read. Introduction You may not have noticed, or even just not paid attention, but when you write code to release the memory space occupied by arrays, you don't have to enter the number of items to be deleted. And it all works great, though.

Data Type Conversions in Java
