Don’t Overpay for Cloud: Six Mistakes To Avoid When Moving to the Cloud

Aggregated on: Tue Mar 28 2023 01:45:04 GMT+0000 (Coordinated Universal Time)

The public cloud is here to stay. Analyst surveys estimate that total public cloud spending will reach US$1T by 2025. The promise of reduced cost, on-demand provisioning, and innovative financial models are key drivers of this growth. However, as with any new technology, there are teething challenges. A pervasive CIO concern has been the seemingly out-of-control and opaque cloud bill and the associated lack of organizational governance around cloud costs. Unfortunately, by the time the CIO intervenes, it’s too late, as the money has already been spent. While optimizing cloud spend requires a hands-on approach to governance and forecasting, it does not require perfect knowledge of the future. The graph below illustrates that reservation-based discounts can deliver cost savings even when you can’t fully predict your upcoming cloud needs.

Technological Advancement in EV (Electric Vehicle) and EV Ecosystem

Aggregated on: Tue Mar 28 2023 01:30:04 GMT+0000 (Coordinated Universal Time)

The Electric Vehicle (EV) Market The Electric Vehicle (EV) current market share is under 5%, which is expected to grow to 24% by 2028, 40% by 2030, and 90% by 2040. Electric vehicle adoption is low due to high cost, limited driving range, and lack of charging infrastructure. The cost of electric vehicles is high. Not all people segment can afford to buy. There needs to be a huge surge in the cost to boost sales. Electric vehicles are powered by batteries. The driving range is limited to battery capacity. This is another major issue. One needs to stop the vehicle to recharge the battery once the maximum distance is reached according to battery capacity. Unlike petrol stations, there are not many EV charging stations. This is another major issue. Hence, it is important to know the nearby charging station before the battery gets drained fully. Unlike ICE-powered vehicles(Gasoline/Petrol or Diesel), Electric vehicle needs an ecosystem approach to drive EV adoption on a large scale. A piecemeal solution may not help. The solution needs to address all the following aspects of the ecosystem.

Orchestration Pattern: Managing Distributed Transactions

Aggregated on: Mon Mar 27 2023 22:15:04 GMT+0000 (Coordinated Universal Time)

As organizations migrate to the cloud, they desire to exploit this on-demand infrastructure to scale their applications. But such migrations are usually complex and need established patterns and control points to manage. In my previous blog posts, I covered a few of the proven designs for cloud applications. In this article, I’ll introduce the Orchestration Pattern (also known as the Orchestrator Pattern) to add to the list. This technique allows the creation of scalable, reliable, and fault-tolerant systems. The approach can help us manage the flow and coordination among components of a distributed system, predominantly in a microservices architecture. Let’s dive into a problem statement to see how this pattern works. Problem Context Consider a legacy monolith retail e-commerce website. This complex monolith consists of multiple subdomains such as shopping baskets, inventory, payments etc. When a client sends a request, the website performs a sequence of operations to fulfil the request. In this traditional architecture, each operation can be described as a method call. The biggest challenge for the application is scaling with the demand. So, the organisation decided to migrate this application to the cloud. However, the monolithic approach that the application uses is too restricted and would limit scaling even in the cloud. Adopting a lift and shift approach to perform migration would not reap the real benefits of the cloud.

Introduction to NoSQL Database

Aggregated on: Mon Mar 27 2023 18:15:04 GMT+0000 (Coordinated Universal Time)

NoSQL stands for "Not Only SQL" and refers to a type of database management system that is designed to handle large volumes of unstructured and semi-structured data. Unlike traditional SQL databases that use a tabular format with predefined schemas, NoSQL databases are schema-less and allow for flexible and dynamic data structures. NoSQL databases are required because they can handle the large volumes and complex data types associated with Big Data. They are designed to scale horizontally by distributing data across many servers, making them well-suited for handling large and growing datasets. Additionally, NoSQL databases are often faster and more efficient than SQL databases for certain types of queries, such as those involving large amounts of data and complex data structures.

Beyond Coding: The 5 Must-Have Skills to Have If You Want to Become a Senior Programmer

Aggregated on: Mon Mar 27 2023 18:15:04 GMT+0000 (Coordinated Universal Time)

In a Nutshell We instinctively equate programming with writing code. Because of it, we focus primarily on code design and creation skills: mastering languages and frameworks, clean code, design patterns, TDD, and architecture. But creating new code is only a fraction of what we do every day. For example, we spend much more time navigating, searching, analyzing, reviewing, and debugging code than writing. Though these activities seem straightforward, they require as specialized skills and experience as coding. Mastering them is what separates true senior programmers from the crowd. And what makes you stand out and get noticed at a new job. In this post, I'll look at the key traits of professional software development, how they impact what you do every day, and explore what skills you need to become a complete programmer. The Common Misconception About Programming People instinctively equate programming with writing code. And it doesn't apply only to lay people. But, unfortunately, many experienced programmers also do have this bias. Not in a naive way, of course. We know that coding isn't just typing and that having crazy keyboard skills doesn't make you a great programmer. But even then, we focus mainly on code creation skills. Think for a moment about what most books, blog posts, and talks are about. What sparks the most heated discussions in your team? What are the most common coding interview questions?

Technologies that were staples in every enterprise back end (e.g., IIOP) have vanished completely with a shift to approaches such as eventual consistency. This shift introduced some complexities with the benefit of greater scalability. The rise of Kubernetes and serverless further cemented this approach: spinning a new container is cheap, turning scalability into a relatively simple problem. Orchestration changed our approach to scalability and facilitated the growth of microservices and observability, two key tools in modern scaling.

What Is Advertised Kafka Address?

Aggregated on: Sun Mar 26 2023 21:30:03 GMT+0000 (Coordinated Universal Time)

Let’s start with the basics. After successfully starting a Redpanda or Apache Kafka® cluster, you want to stream data into it right away. No matter what tool and language you chose, you will immediately be asked for a list of bootstrap servers for your client to connect to it. This bootstrap server is just for your client to initiate the connection to one of the brokers in the cluster, and then it will provide your client with initial sets of metadata. The metadata tells the client the currently available brokers, and which the leader of each partition is hosted by which brokers so that the client can initiate a direct connection to all brokers individually. The diagram below will give you a better idea.

ClickHouse: A Blazingly Fast DBMS With Full SQL Join Support

Aggregated on: Fri Mar 24 2023 21:30:02 GMT+0000 (Coordinated Universal Time)

ClickHouse is an open-source real-time analytics database built and optimized for use cases requiring super-low latency analytical queries over large amounts of data. To achieve the best possible performance for analytical applications, combining tables in a data denormalization process is typical. Flattened tables help minimize query latency by avoiding joins at the cost of incremental ETL complexity, typically acceptable in return for sub-second queries. However, denormalizing data isn't always practical for some workloads, for instance, those coming from more traditional data warehouses. Sometimes, part of the source data for analytical queries needs to remain normalized. These normalized tables take less storage and provide flexibility with data combinations, but they require joins at query time for certain types of analysis.

Implementing PEG in Java

Aggregated on: Fri Mar 24 2023 18:45:02 GMT+0000 (Coordinated Universal Time)

In Part 1 of the series on PEG implementation, I explained the basics of Parser Expression Grammar and how to implement it in JavaScript. This second part of the series is focused on implementation in Java using the parboiled library. We will try to build the same example for parsing arithmetic expressions but using different syntax and API. QuickStart parboiled is a lightweight and easy-to-use library to parse text input based on formal rules defined using Parser Expression Grammar. Unlike other parsers that use external grammar definition, parboiled provides a quick DSL (domain-specific language) to define grammar rules that can be used to generate parser rules on the runtime. This approach helps to avoid separate parsing and lexing phases and also does not require additional build steps.

Loop Device in Linux

Aggregated on: Fri Mar 24 2023 18:45:02 GMT+0000 (Coordinated Universal Time)

Overview If you have ever downloaded a new Linux distribution ISO image, you may have wondered how to access the contents inside the image prior to repartitioning your disk and installing the operating system onto your local disk. This can be done via a loop mount in Linux. In Linux and other UNIX-like systems, it is possible to use a regular file as a block device. A loop device is a virtual or pseudo-device which enables a regular file to be accessed as a block device. Say you want to create a Linux file system but do not have a free disk partition available. In such a case, you can create a regular file on the disk and create a loop device using this file. The device node listing for the new pseudo-device can be seen under/dev. This loop device can then be used to create a new file system. The file system can be mounted, and its contents can be accessed using normal file system APIs.

However, while much attention is given to the technical aspects of MLOps, what's often overlooked is the importance of the operations. There is often a lack of discussion around the operations needed for machine learning (ML) in production and monitoring specifically. Things like accountability for AI performance, timely alerts for relevant stakeholders, and the establishment of necessary processes to resolve issues are often disregarded for discussions about specific tools and tech stacks. ML teams have traditionally been research-oriented, focusing heavily on training models to achieve high testing scores. However, once the model is ready to be deployed in real business processes and applications, the culture around establishing production-oriented operations is lacking. As a consequence, there is a lack of clarity regarding who is responsible for the models' outcomes and performance. Without the right operations in place, even the most advanced tools and technology won't be enough to ensure healthy governance for your AI-driven processes.

All We Can Aim for Is Confidence Releasing features is all about confidence: confidence that features work as expected; confidence that our work is based on quality code; confidence that our code is easily maintainable and extendable; and confidence that our releases will make happy customers. Development teams develop and test their features to the best of their abilities so that quality releases occur within a timeframe. The confidence matrix shown below depicts four main areas:

This is an article from DZone's 2023 Software Integration Trend Report.For more: Read the Report In recent years, the rise of microservices has drastically changed the way we build and deploy software. The most important aspect of this shift has been the move from traditional API architectures driven by monolithic applications to containerized microservices. This shift not only improved the scalability and flexibility of our systems, but it has also given rise to new ways of software development and deployment approaches.

The .NET framework has come a long way since its inception, and as newer versions are releasing quite frequently, it becomes increasingly important to keep up with the latest updates. As technology advances, software applications must keep up with the pace of change to remain relevant and effective. Legacy .NET applications that were developed on older versions of the framework can greatly benefit in terms of performance, enhanced security, and taking advantage of new features and improvements by upgrading to the latest version. Note: In this article, I mainly focus on .NET console applications and class library projects. For upgrading ASP.NET applications step by step, I will create a separate article.
