Developing a Cloud Adoption Strategy

Aggregated on: 2022-08-02 20:21:41

The value of technology in businesses and organisations cannot be underestimated, and there was nothing like the COVID-19 pandemic for us to see its value first-hand. Overnight, the way we interact with and operate businesses was forcefully changed forever, effectively accelerating our journey towards digitally transforming our organisations. According to a 2020 McKinsey report, companies were able to adopt digital changes 20-25 times faster than they would have anticipated.

Trending Programming Language to Learn

Aggregated on: 2022-08-02 19:51:41

It wasn't that long ago when computer programming was an almost unknown and secluded field. Back then, there used to be only a few people who had the advanced coding skill set to be considered computer programmers. But today, information technology is evolving at a faster pace than ever before. In parallel with the rapid development of the IT sector, there is a rapid growth in the market demand for specialists.

Comparing Approaches to Durability in Low Latency Messaging Queues

Aggregated on: 2022-08-02 18:51:41

A significant feature of Chronicle Queue Enterprise is support for TCP replication across multiple servers to ensure the high availability of application infrastructure. I have generally held the view that replicating data to a secondary system is faster than sync-ing to disk, assuming the round trip network delay wasn’t high due to quality networks and co-located redundant servers. This is the first time I have benchmarked it with a realistic example. Little’s Law and Why Latency Matters In many cases, the assumption is that as long as throughput is high enough, the latency won’t be a problem. However, latency is often a key factor in why the throughput isn’t high enough.

The Essential Web3 Tools and Technologies Developers Must Know

Aggregated on: 2022-08-02 18:51:41

Web3 is the next iteration of the web. As opposed to Web1, which consisted of static web pages, and Web2, which brought us web apps and the web as a platform, Web3 consists of decentralized networks built on blockchains. There is a high demand for Web3 developers, as relatively few current developers are experts in this field. So if you’re an established Web2 engineer wanting to break into Web3, where would you start? What are the fundamental concepts to know, and what tools and technologies would you need to learn?

This article on cloud storage is typical to a beginner's compass and will serve as a reference resource for anyone seeking sufficient knowledge about the cloud.

Externalize Microservice Configuration With Spring Cloud Config

Aggregated on: 2022-08-02 14:21:41

In a microservices system, we might need or want to externalize configuration so that we can abstract sensitive data or credentials outside the applications. We can do something like this with Docker Compose, but the compose file often contains values for multiple services together. We probably want further separation and limited access. This is where solutions such as Spring Cloud Config come into play. We have a free Neo4j graph database instance on a public cloud, so we can set the credentials in an external location (such as a local file or other systems) and use Spring Cloud Config to access those keys and pass them to the approved application.

In this article, we will see how we can integrate MuleSoft application logs with the external data system using the Log4j2 file. Some organizations want to persist logs for more than 30 days or want to build custom dashboards based on the logs; hence, there is a need to store these logs in an external data system. The easiest and most recommended way to integrate the logs with external systems is through the Log4j2 file.

Java Class Loading: Performance Impact

Aggregated on: 2022-08-01 19:36:41

java.lang.ClassLoader#loadClass() API is used by 3rd party libraries, JDBC Drivers, frameworks, and application servers to load a java class into the memory. Application developers don’t use this API frequently. However when they use the APIs such as ‘java.lang.Class.forName()’ or ‘org.springframework.util.ClassUtils.forName()’, they internally call this ‘java.lang.ClassLoader#loadClass()’ API. Frequent usage of this API amongst different threads at runtime can slow down your application performance. Sometimes it can even make the entire application unresponsive. In this post let’s understand this API a little bit more and its performance impact.

You Are Blind to the Risks in Your Cloud — Why Companies Need Cloud Security Monitoring

Aggregated on: 2022-08-01 18:51:41

Migrating to the public cloud can be a risky endeavor because it decentralizes or expands a business’s attack surface. In other words, the move can expose businesses to a variety of new ways bad actors can exploit vulnerabilities or poorly configured cloud settings. With that in mind, an effective cloud security monitoring strategy is critical to business success. To put it simply, cloud security monitoring is critical to protect your data in the public cloud.

Are Prometheus Recording Rules the Right Tool for the Job?

Aggregated on: 2022-08-01 18:06:41

If you’ve used Prometheus in the past for metrics collection/monitoring, then you’re probably familiar with Prometheus recording rules. As the Prometheus documentation says, recording rules allow you to precompute frequently needed or computationally expensive expressions and save their result as a new set of time series. Recording rules are the go-to approach for speeding up the performance of queries that take too long to return, and they are also commonly used to alias complex or repetitive PromQL subexpressions. While recording rules can be quite useful and are almost certainly in use in any production environment, they do have some downsides as well. In this post, we’ll take a look at how recording rules work, and discuss some of the pain points that you are likely to encounter when your workload scales up. How Recording Rules Work So, how do recording rules work? Recording rules are defined in YAML files that are referenced by the rule_files option in the Prometheus configuration file. Rules are structured into named groups, with each group having the ability to set the evaluation interval (default is 60s, as specified by the evaluation_interval option in the Prometheus configuration file), and an optional limit on the number of series that can be generated by the rules in the group. As part of the Prometheus server’s regular operation, it evaluates the provided rules on a schedule according to the configured evaluation interval for each group.

The Need for a Kubernetes Alternative

Kubernetes has become a household name for container orchestration. There is no denying that it has risen to become an ideal solution for many developers. But is Kubernetes truly flawless? On the contrary, you can go from being enthusiastic about the possibilities Kubernetes offers to being frustrated trying to resolve the many issues that come up along the way. This is why an increasing number of organizations have begun to look for more easy-to-use Kubernetes alternatives. This article highlights the need for these alternatives and puts forward a strong contender to replace Kubernetes. Source: Pixabay

What to Know About Python and Why Its the Most Popular Today

Aggregated on: 2022-08-01 16:06:41

What Is Python? Python is said to be a high-level and general-purpose programming language. It supports several programming paradigms, as well as structured, object-oriented, and functional programming. It is used for Data Science, Data Analysis, Machine Learning, Software Development, etc. Guido van Rossum created Python in 1991 as Python 0.9.0 which was the first released. Python 2 is a very popular version and its latest version is Python 3.

Observability Tools Help Catch Application Failures — But Automating the Observer Is Becoming Crucial

Aggregated on: 2022-08-01 14:36:41

A modern-day blessing for Site Reliability Engineers (SREs) entreats, “May the queries flow, and the pager stay silent.” This is because SREs, DevOps engineers, or support staff are constantly stressed about responding to their alert channels while keeping an eye on operational and performance dashboards to ensure their users have a good experience. Many frontline engineers are glued to dashboard monitor screens laid out in front of them. Assessing and responding to alerts is a top priority. This approach involves both the observability tool and the observer, and they both have crucial roles. While various golden signals are continually monitored on the observability dashboards, it is up to the observer to provide the evaluation and intelligence to piece together details and know when and how to respond. This is especially apparent when there is some kind of problem. The observer has to determine what to drill down on and then where to go next in order to find the root cause. The observer is decidedly not automated, and there are finite limits to what they can take in and consider in their observations to develop proper context, validation, and, ultimately, to understand the root cause of a problem.

We wanted to tackle one of the major challenges facing organizations: on-call. "SRE: From Theory to Practice - What’s Difficult About On-call" sees Blameless engineers Kurt Andersen and Matt Davis joined by Yvonne Lam, staff software engineer at Kong, and Charles Cary, CEO of Shoreline, for a fireside chat about everything on-call. As software becomes more ubiquitous and necessary in our lives, our standards for reliability grow alongside it. It’s no longer acceptable for an app to go down for days, or even hours. But incidents are inevitable in such complex systems, and automated incident response can’t handle every problem.

GraphQL in Enterprise: What It Takes to Build, Deploy, and Monitor a New Enterprise GraphQL Service

Aggregated on: 2022-08-01 03:36:41

New technologies always require some planning, changes, and experimentation before they merge into an enterprise stack. GraphQL adoption has been no exception to this. Companies like Airbnb, Netflix, Shopify, and other industry giants have all taken the leap to use this promising technology. In this article, I will outline a few key considerations for creating your new service, deploying it, and monitoring the service. This assumes that you have a basic understanding of what GraphQL is, some of the key use cases, and awareness of some of the concerns in regards to adoption. With that in mind, let’s jump in. GraphQL vs. REST Before you begin to build your GraphQL service, it’s important to consider the reigning approach for building Web APIs: REST. A common misconception about GraphQL is that it is a replacement for REST. Thinking of the technology in this light would be very wrong. Both GraphQL and REST can be very complimentary and most enterprises will use a mixture of both approaches.

On the other hand, we have the most popular paradigms in the code, especially when we talk about enterprise OOP. How do you combine both archive and software design, primarily on Java? This article will explore more details on code, especially inside the Jakarta EE world, mainly to answer the questions in a previous Jakarta JPA discussion: should we have a constructor on JPA, and why?

Debugging a Wordle Bug

Aggregated on: 2022-07-31 21:06:41

I have a confession: I'm addicted to Wordle. Especially now that it's out of style and people don't post about it. I love that it's short, I can solve one word, and then it's gone. I don't feel bad about the addiction and wasting my time with any game. This cloud debugger tutorial is an enormous challenge for me since the target is a Wordle game. But I'm getting ahead of myself. As part of the Lightrun Playground, we recently released we needed a demo application that will let developers who are new to Lightrun, practice in a "safe environment".We decided to pick Wordle as our demo application because it's instantly familiar, visual, and not too interactive. A Flappy Bird demo might have been painful to debug. At this point, our key challenge was in creating a bug where the debugging process would be interesting enough and yet subtle enough so it won't be instantly obvious.

Optional in Java - When Better Code Is Not an Alternative

Aggregated on: 2022-07-31 20:06:40

If you are a Java developer, you have handled issues with Java for a long time. The most often problem in the Java world is the NullPointerException. Nullity is a natural consequence of reference types. If there is a reference, it has to refer to some object - or be null. If there is no this option, all the variable was initialized with some non-null expression - and even then, you'd have issues if variables were read during the initialization phase.

IT modernization and innovative new technologies change the healthcare industry significantly. This blog series explores how data streaming with Apache Kafka enables real-time data processing and business process automation. Real-world examples show how traditional enterprises and startups increase efficiency, reduce cost, and improve the human experience across the healthcare value chain, including pharma, insurance, providers, retail, and manufacturing. This is part five: Open API and Omnichannel. Examples include Care.com and Invitae. Blog Series - Kafka in Healthcare Many healthcare companies leverage Kafka today. Use cases exist in every domain across the healthcare value chain. Most companies deploy data streaming in different business domains. Use cases often overlap. I tried to categorize a few real-world deployments into different technical scenarios and added a few real-world examples:

Deriving Ideal Indexes: A Guide

Aggregated on: 2022-07-30 17:21:40

Indexes are there to simplify our work when searching for data: they speed up SELECT queries at the expense of slowing down other kinds of queries like DELETEs, UPDATEs, and INSERT s instead. However, as awesome as indexes might be, they also need a lot of work to get right — in this blog, we will tell you how you should go about deriving ideal indexes for your database. The majority of the examples in this article will focus on MySQL: however, the concept is the same for all major database management systems available on the market today. What Are Indexes? If you are familiar with database structures, great — because that's essentially what indexes are! Indexes are database structures that can be used to quickly find rows having specific column values. At the expense of taking up disk space and time if your tables are big and you find yourself adding indexes on top of them, indexes allow databases to skip reading through entire tables and instead, only scan relevant rows which means that databases have less data to scan through.

Securing Container Base Images Using Kyverno Policies

Aggregated on: 2022-07-30 17:21:40

Before jumping into the details, it’s worth explaining what the “Base Image” term refers to. Words matter, there is some misunderstanding between the terms “Parent” and “Base” image. As defined by the Docker documentation, a parent of an image is the image used to start the build of the current image, typically the image identified in the FROM directive in the Dockerfile. If the parent image is SCRATCH, then the image is considered a base image. However, the terms “base image” and “parent image” are often used interchangeably in the container community.

Upgrading Kubernetes Clusters With Cluster API on Oracle Cloud

I’ll be totally honest, I’ve manually upgraded a Kubernetes cluster, it wasn’t the end of the world, but I’m a lazy hacker so why do it manually when I can automate it and have the safety of repeatability?

Differences Between Windows and SQL Server Authentication

Aggregated on: 2022-07-30 15:51:40

Authentication is a crucial aspect of any security strategy. It is a process or act of proving that a specific person’s identity is true, valid, or genuine. To put it simply, it is an act of determining whether someone or something is what it actually claims to be. When it comes to Microsoft SQL Server, there are two different modes of authentication, namely Windows mode and mixed mode. These two modes determine how the system authenticates or identifies a particular user.

Common Mistakes to Avoid When Migrating

Aggregated on: 2022-07-30 15:51:40

For enterprises, being able to migrate thousands of applications is an inevitable part of staying competitive. Figuring out how to achieve a successful migration is scary so let’s dive into the pitfalls to avoid. COVID-19 has created both a technical talent shortage combined with an increase in demand for accelerated technical timelines. Many companies are starting to face a “Red Queen” effect, where companies are having to re-define how and where they are competing in the market to ensure they remain relevant. Today businesses that remain complacent are rewarded with a biting disadvantage and a perpetual catchup cycle. Migrations from incumbent technologies to more responsive and cost-effective solutions are a significant part of any enterprise’s metamorphosis; however, it can be fraught with pitfalls for the unprepared.

How Do You Know If a Graph Database Solves the Problem?

Aggregated on: 2022-07-30 15:21:40

One of the greatest questions to consistently badger a developer is "what technology should I use?". Days of thought and analysis determines which option(s) (from an increasingly growing number) best suits the need, manages volume and demand, plans for long-term strategy, simplifies/reduces support, and gets approved by colleagues and management. Those steps may even seem easy compared to real life. The decision's complexity can get compounded by how much buy-in is needed, and the current constraints of existing technology plus developer knowledge. For instance, investing in an unknown or newer solution means allocation for learning costs.

External Debugging Tools 3: JMXTerm

Aggregated on: 2022-07-30 14:21:40

When tracking a bug we need to take a two-pronged approach. Similar to tongs that wrap the buggy module from both sides and squeezes to find the problematic part. Up until now, we discussed tools that are very low level. Some can be used to debug system-level services. Today we’ll discuss the other side of the stack but still a very advanced management tool. To understand this you need to understand the field we’re in. As developers, we deal with code and applications. Deployment is for OPS/DevOps and the tooling they use is often alien to us. It’s not that they have bad tools. On the contrary, they have amazing tools. But they’re usually designed for massive scale. When you need to manage thousands of servers you need a way to control things in all of them. For that, we need a different set of tools.

Data Model Tracing and Reporting on a Relational Database

Aggregated on: 2022-07-29 17:51:39

In relational databases, data is stored on tables created with a certain model and relationship network. Especially in systems that are not fully mature yet, changes in data models occur frequently and they make it difficult to control data and data models in terms of integrity, consistency, and granularity. This necessitates control mechanisms that will work on the basis of changes made to the data model and a catalog mechanism. The control mechanisms mentioned above should not block the development processes, but should also prevent the data model from turning into "garbage." In this respect, the data model (table names, existence of related tables and their compatibility with each other, consistency of related tables in terms of columns, etc.) should be considered in the planning to be made.

Build a Java Microservice With AuraDB Free

Aggregated on: 2022-07-29 14:21:39

For today’s adventure, we want to build a Java microservice that connects to and interacts with graph data in a Neo4j AuraDB Free database. Our data is a trimmed-down version of the Goodreads data set, which includes the book, author, and review information. While books and authors are well-suited for a document database such as MongoDB, once you add reviews to the mix, the nuance of the relationships makes this project better suited for AuraDB. This way, we can utilize relationships between the different entities to improve analysis based on the structure of the connections. While everything we will do here is feasible with other data stores, a graph database dramatically simplifies queries into how entities are connected. If you are new to graphs, here are some resources:

Using Ingest Pipelines to Enhance Elastic Observability Data

Aggregated on: 2022-07-29 05:36:39

In a previous article, I had written about distributed tracing and how it can be implemented easily on the Elastic stack. I have used many observability platforms, including NewRelic, Splunk, and DataDog. All of them are very powerful platforms and have everything you would need for implementing full-stack observability for your applications. Elastic is generally used for fast and powerful content search and log aggregation and analysis, but it has gained popularity recently for full-stack observability as well. It has pretty much every feature you would want in an observability platform, including support for applications written on a modern tech stack, support for tracing/logging/metrics, powerful out-of-the-box agents, visualizations and dashboards, alerting, AI-based anomaly detection, and so on.

How to Leverage Speech-to-Text With Node.js

Aggregated on: 2022-07-29 04:06:39

The purpose of this article is to provide a brief overview of speech recognition technology and its common applications, and to demonstrate a free speech-to-text API which can be used to transcribe audio in MP3 and WAV file formats. This demonstration will include step-by-step instructions to call this API using ready-to-run Node.js code examples. Overview of Speech Recognition It’s easy to think of speech recognition as a relatively new addition to the contemporary technology landscape. That’s only a partial truth; speech recognition mechanics have been around for more than half a century, beginning with basic, limited numerical/word recognition systems developed by a few pioneering technology companies during the early 1950s. Despite its long history and proliferation in the world of smart consumer devices over the last decade or so, however, speech recognition still registers as one of the more abstract technologies on the market today. That’s because all speech recognition services straddle the fields of computer science, computational linguistics, and mathematics/statistics, requiring sizable input from each field to achieve accurate speech-to-text results.
