TOP 5 JAVA ANOMALY DETECTION TOOLS

Application failures are a certain part of their development. Every developer has faced some errors that crop up as we move forwards. But wouldn’t it be better if the abnormal were detected in real-time and you were warned? Even better, if you could find out what went wrong and where? Luckily, Java Developers from India have quite a few abnormal tools that can help course true in time.

Top Five Java Anomaly Detection Tools

1) X-Pack

An extension of Elastic Stack, X-Pack is necessarily a security characteristic. It works by monitoring logs for data. It monitors, alerts, and reports on the behavior of the logs. It uses machine learning algorithms to monitor log behavior and flag any unusual behavior. The X-Pack also has graph capabilities, using metrics to illustrate user behavior.

It creates a basic behavior pattern by studying data from Elasticsearch logs. The logs are, in turn, culled from servers and applications. The data shows us trends and usage patterns. Any deviation from the pattern helps predict the onset of a problem.

X-Pac is also fantastic easy to install. With Elasticsearch 5.0.0, whenever you install X-Pack, you automatically get access to Watcher, Marvel, and Shieldplugins. Moreover, you also do not have to worry about the plugin version, since it now comes with the X-Pac. With a default detection feature, X-Pac has also tightened user authority. Keep in mind that X-Pac is necessarily an ELK tool and is well-integrated in its architecture. However, it is not as effective if you are out of ELK.

2) Loom Systems

Powered by AI, Loom Systems use log analysis to compare and predict issues that can crop up in the development of an application. It automatically takes logs from applications and breaks them down according to different fields. The parsing of any streamed log is automatic. The AI function then compares the events between different applications, exposing any issues and helping in the prediction of anomalies.

The data is examined according to the field type. The advantage of Loom Systems is its usage of AI to pinpoint the root cause in real-time, allowing you to take corrective action in time. It uses the organizational database to explain the anomaly and provide you with recommended solutions. The Loom also ensures that the baseline remains dynamic, changing as the standard user behavior changes.

The Loom system has many positives – its dynamic baseline that evolves with time, a superior analytic component that exposes flaws and makes us understand why it occurred, and its ability to provide you with an effective solution.

3) OverOps

So far we have only seen tools that detect errors in the log. But what you really need is the source of the error and what caused it. The answer lies in OverOps. Instead of logs, it focuses on the source code and the variable state that causes the error.

The OverOps scores because it is the only tool that focuses on code. It detects when and where a code breaks during the production process. Thus, it gives us a complete picture of the anomaly, helping us to pinpoint the instance it occurred in the code deployment.

It is also pretty easy to install, taking no time in SaaS, Hybrid, and On-premises. It can be hosted as a SaaS application, or deployed on-premises. You may even choose it simply for its uber-cool dashboard. It works with StatsD compliant tools for visualization of anomaly detection.

Working with the JVM, OverOps extracts data from the applications. It compares the variable state with the JVM metrics, showing application errors. OverOps also has a collaborative add-on, providing links for errors in the logs as well. The link takes you to the very cause of the error with the source code.

4) Coralogix

Coralogix uses AI to show segregate the logs into patterns and show their flow, giving us an insight in real-time. While mapping the production flow, Coralogix can instantly detect the moment an issue occurs, giving us precise insight.

Showing the original pattern in the log data also helps in the analysis of Big Data. It works on the assumption that most logs show similar patterns. The process brings out the big anomalies and not every small issue.

5) Anodot

Anodot uses AI to uncover blind spots. It uses patented machine learning algorithms to deliver BI. The company boasts of revolutionary BI that uses your metrics and applies machine learning to analyze the data. Anomalies are detected instantly and an alert is triggered.

DEBUNKING THE MYTH: EXPLORING JAVA 9 MISCONCEPTIONS

Java is doubtlessly one of the top-most programming languages in the world. Despite its beginning as a program for set-top boxes, it remains one of the most widely used languages. It is not just preferred by programmers and coders, it is also a popular language when it comes to teaching programming languages in schools and universities.

But Java also comes with too much of myths and misconceptions. Some of it is inevitable with a popular language where murmurs on its features and efficiency become Chinese whispers. But some also stock from its beginning as a simple language that looked too good to be true. Its creator’s bold announcement of “write once, run anywhere” was considered a bit too revolutionary.

Although Java has come far since its starting – now with Java 9, the misunderstanding surrounding it is still quite prevalent. This is despite the fact that many programmers chose to keep working on Java and you can easily hire java developers for enterprise application development.

Let’s check some of these myths:

Java is dead

We’ll call this is the strangest myths regarding Java that refuses to die down despite the fact that rates among the top programming languages used across the world. Don’t take our word for it. Check out the RedMonk Programming Language Ranking the TIOBE index which has repeatedly found Java among the topmost popular languages. Java remains alive and thriving.

Java is slow

This one has some basis in truth and it stems from the JVM or the Java Virtual Machine. One of Java’s USPs was “write once, run anywhere”. But this depended on the JVM that gave it the cross-platform portability. But JVM also meant an additional infrastructure layer, which would obviously slow down the entire process. In addition, some early JVMs were actually pretty slow.

But the scenario is quite different now. The new JVMs are quite fast. The speed of our hardware also means that the delay is negligible. It may matter in applications where every second counts, but for most applications, Java’s speed is a complete non-issue.

Java suffers no memory leaks

When we compare it with C and C++, Java seems pretty foolproof against memory leaks. In the other two languages memory leaks can occur anytime there is an error in allocating the location. Since this is done by the programmer, simple human error makes the possibility of a memory leak ever-present. Java removes the human factor by automating memory management. The garbage collector later does the clean-up for objects with no references.

However, the clean-up depends on the reference and if a reference remains, the garbage collector will skip it. In effect, this will be the same as a memory leak. Finally, it will run out of free memory. So, though it may have better memory management, a programmer can’t provide to ignore cleaning-up.

Java cannot be embedded because it’s too big

It started with 20 class libraries and now Java 9 has more than 6000! These are critical support bases since Java cannot depend on a specific platform-based library. For Java developers, the libraries are especially handy since there is little need to take support of a third party. But it did make Java’s size very big. Full JRE took as much as 40MB of storage space.

But Java has addressed this issue actively in its last few versions. Java 8 introduced solid profiles, the smallest of which would need just 10 MB. Java 9 has created a modular format so that one can pick and choose what one wants, restraining the size.

Java is not secure

This idea gained traction when an idea was floated that an applet can easily access a hard drive. With this came scares of corruption and even erasures. But, in truth Java security is not that light. An applet cannot access the system with impunity. There are checks and balances to prevent this. A digitally signed applet will trigger warning systems in the OS, asking the user if they acknowledge it.

Conclusion

Java has been around long sufficient to develop its own mythology. From the sole language that can fix it all to its features and functionality, there are obviously many myths associated with Java. While some may have come from earlier versions, others are just not true.

How to Use Spring Batch and Connect It to Database in Java Development?

Implementing a batch process for managing gigabytes of data is no doubt a hectic job. Spring Batch is a renowned module that has been intended to manage batch processing details for all kinds of files. You can start with Spring Batch by developing a simple importing job, which will import the products from CSV file and send them to the MySQL database. Later explore the batch processing capabilities using one or multiple processors and helpful tasks. In the end, you can have a quick overview of the resiliency tools in Spring Batch for retrying records, skipping records, and restarting batch jobs.

A batch processing system has to manage huge amounts of data, handle the individual record’s failure without breaking down the entire process, and manage pauses and restarts without re-doing already done tasks. However, Spring Batch assistance makes the job easier for Java developers.

Job of the Spring Batch system

The core processing of Spring Batch involves distinct steps-

1. Reading

2. Processing

3. Writing

How to connect Spring Batch to a database?

Spring Batch maintains a tables set that is used to record the present or ongoing state of jobs and the processed records. In case a job needs to be restarted, with Spring Batch, it can continue from where it paused.

Spring Batch can connect to any database of your choice; however, we are using MYSQL. You can download the community version for free as it will meet your requirements. Once the setup is installed, you will need to develop a database and a user that has permissions to communicate with that database. You need to launch MySQL from the command line, from MySQL’s bin directory and implement the following code:

create database spring_batch_example;
create user 'sbe'@'localhost' identified by 'sbe';
grant all on spring_batch_example.* to 'sbe'@'localhost';

The starting line develops a new database – spring_batch_example, this database will maintain your products. The second code line will develop a user- sbe with the password sbe. The end line allows sbe user to access the spring_batch_example database.

Why Java Development company Uses Real time system Over Standard Java VM and C++

Aegis, a leading Java development company shares advantages and features offered by Java RTS to developers and entire community across the world. In this post, professionals will explain all the advantages and latest features launched by real time system.

Java Real time system empowers real-time app developers to make maximum utilization of Java while maintaining the predictability of present RTS development platforms, like QNX, and more custom embedded systems. It allows sharing data on a single system and coexisting real-time components and non real time components. All the features of Java RTS are delivered through a separate version of the Java VM, which can process Java RTS and Java SE components and provide flexibility to the developers.

Are you aware of the term “Real Time?”

RTC (Real time computing) is the study of software and hardware systems related to a real time constraint, for example operational time frame for event-to-system response unlike non RTS software. Most people get confused in real time and real fast. Speedy performance is not a must thing for some RTS. For example- a financial institute may carry out settlement processing once a day – probably at the end of a day; it is hardly required speedy performance. The term real time is about developing systems having deterministic behavior, guaranteed response time and predictability by hiring expert java developers. In case there is a need to check the event once a day or every millisecond, predictability prevents unforeseen delays, latency and unwanted interruptions.

A Java development company brings two basic RTS types- Hard and Soft.

The hard RTS usually experience severe failure in case the user violates the time constraints. User has to carry out operations in correct way and within the time constraints to get successful outcomes. If the user crosses the deadline, its value will get null to the system. The soft RTS are flexible and some latency is acceptable; however, you still need to consider system predictability. In short, hard real time systems need instant system response and soft real time systems are able to withstand some bounded latency.

Developers of RTS applications often depend on software framework, java programming language, operating system or all of three things to attain real-time behavior in their developed apps. For instance, developers use Nucleus, QNX, VxWorks, Solaris, and more environments due to the list of tools and libraries support for RTS app development.

Java RTS meets both the soft and hard RT needs and needs a particular JVM to run. It still sustains comprehensive compatibility with existing Java SE 5 apps. Moreover, user can run standard Java SE apps in the same JVM besides developed apps to use its real time facilities.

Benefits and additional features of RTS:

• RealtimeThread thread class
• Java SE 5 compatibility
• Model of ScopedMemory
• Model of ImmortalMemory
• High-resolution timers
• Asynchronous event handlers

Aegis is a premium Java development company having a staff of qualified developers and programmers. You can explore the services and ask anything related to real-time java development from our experts. If you have anything to share with us, just share- we are waiting for your response.

Why Enterprises Should Hire Java Developers That Possess Core Experience in Top Ranking Java Frameworks

Java frameworks play essential role in app development. These are prominent chunks of pre-written code used by hired Java developers in order to solve domain related issues. Java has different kinds of frameworks and it is important for developers to know the use of such frameworks and steps to solve issues. That’s why companies give more preference to hire java developers who possess clarity for using frameworks in different situations. These are the backbone of an application and a developer must have acquired least experience of using framework for java web development.

Why enterprises think that instead of hiring a team for development, they should hire seasoned java developers?

Bigger enterprises often entertain java developers who possess heavy portfolio. They prefer to hire java developers who can instantly troubleshoot and solve the issues faster than a team and save their cost. When it comes to Java framework, it is good to consider the capability of a developer and his way of using the framework. It’s because Java programming language offers different frameworks and your hired java developer should attain basic knowledge for using them in certain situations.

Here we will discuss top 7 Java frameworks that developers across the world prefer to work with:

• Java Server Faces- There is a great demand of developers having experience in JSF framework as it represents UI components, supports accessibility, converts value and supports internalization.
• Apache Struts 2- This framework is intentionally designed to synch sorts of components of app development lifecycle. Small teams working in an enterprise often use this framework.
• Spring MVC- This framework brings integration of technologies and is deployed to various development projects.
• Stripes- This framework provides provision for intense conversion, validation and binding. The hired Java developers use Stripes to solve indexed properties, domain objects, and localization related issues.
• Wicket- It is used for programming purposes and under this, each component supports its own model and that’s why developers prefer this framework to use development resources.
• RIFE- This separates the operations during the development process and integrates them flawlessly with other operations.
• Tapestry- It is used by expert java developers to create cutting edge app solutions. This is an advanced framework and every developer has a dream to try his hands on Tapestry.

It is difficult to find and hire java programmers who had worked on all of these frameworks. Still, enterprises try and hire the best java developers for their premises.
