.Net Developers In India – Need Of The Hour

India has become the hub of technology, in fact the youth of today is synonymous with the IT generation.IT is regarded as one of the most lucrative career option which also provides an easy connect to the western nations.

With technology fast evolving, the internet and the cloud have seen a lot of advancements however the fundamentals still remain the same. This goes well with .net as well. There are already loads of .net developers in India and the demand is still growing as .NET is a very widely used language.

Apart from just offshore demand there is a lot of outsourcing demand for software professionals who are regularly needed to work both onsite as well as offshore. As we all are aware, that there is a huge supply of software professionals in India which leads to a competitive advantage for India. Therefore, India is able to provide its software development services at a cheaper price as compared to from the western countries, which leads to outsourcing of all the development work from all over the world to India.web dev .net

Why Is .NET Suitable In Various Industries?

  • We all are aware that .NET is one of the most preferred languages as far as development is concerned.However the big question is why it is one of the most desired languages. There are very many reason for it to be so.Few of the reasons are because of growing web technology and growing virtual presence of business and customers, customers extensive knowledge and readiness to learn and adapt and the growth of business which now require a must robust platform to sell their services.
  • .NET is one of the most preferred languages and very versatile and is widely being used in B2C and B2B ,along with many eCommerce businesses. ASP.Net us also very suitable for research and marketing purpose such as polls and survey website which aims at capturing the views of the audience. Other than that it plays a very vital role in CMS, newsletters and forums, as it is easy to comprehend and understand.
  • Other than functionality, .NET works out to be more feasible as compared to its counterpart as it requires less rework and has a greater appeal factor.

.Net developers in India are very much in demand because of their caliber and growing need and demand for the language. There are many ways buy which they are paid, however broadly two ways are much more in use which is pay per hour and a predicated project based cost.

These negotiations are normally left for the senior management to do, basically the .net developers in India are generally paid a monthly salary unlike contractors who work on a fixed price per day or project. Last but not the least, technology has previously changed and will definitely change and evolve according to the changing environment, however a budding .net developer must always understand the importance of fundamentals, as the fundamentals never change ,it’s just the way how they are used changes.

Why Java Developers Need Java Messaging System?

This post shares info on Java Messaging System. Java developers are using it in their practice for several reasons. You can read the post and find the reasons.

Why messaging system?

In the electronics world, data is the actual term used for all information. For which data, “Message” term can be used? Let’s take simple scenario, if you are registering your details in the web portal, it takes all your information and store entire data in relational database which will be called as a Data. Once you registered successfully, an email functionality triggers and send an email to you saying that account is successfully created. This email event is called as messaging.

In traditional system, both registering new user and sending email are tightly coupled i.e. both are in same application. This design is extremely responsible for the system’s performance. Imagine 100s of user registering in 15 minutes, the same application should focus creating new user and sending email. This process is too costly. To avoid this issue, messaging systems are come into picture.

 It runs independently and just looks up for the message and doesn’t care about where messages are coming from. If the message arrives, it consumes the message and sends it to destination. This is called as loosely coupled and both applications run independently.

The responsibility of Web Portal is to create new user and to send email to user is messaging system’s responsibility. Messaging system is not only used for sending email. There are many scenarios where we need Messaging system such as notification, news feed etc.

There are many messaging system in the market. Rabbit MQ is one of such popular messaging systems in Java, which includes three roles – publisher, subscriber and queue.

Publisher is the one who sends the message. The sent message will store in temporally in a buffer called queue. Subscriber is the one who receives the message. The Rabbit MQ is having all these players that are required for messaging service.

Why we need Apache Kafka?

Since there are more matured messaging systems available in the world, why we need Apache Kafka? That’s a question that triggers developer’s mind.

The other messaging systems handle only low volume data. But Rabbit MQ handles 20K messages per second. Apache kafka handle 100K messages per second. Kafka provides easy way to create many kafka clusters which is called as broker. This is for maintaining load balance. If one broker gets down, the other automatically takes care.

Apache kafka persists the messages in hard disk and java developers can set life time of message.

Following players are included in the Apache Kafka in messaging system-

  • Topics
  • Producer
  • Brokers
  • Consumer

Topics

Topics hold the stream of messages. For example Topic “A” can hold the message “Hello World”. If we create a topic, kafka creates by default one partition. Partition contains sequence of index in which messages are get stored. Based on our requirement we can create many partitions in Topics as in the diagram.

Topic “A”

Partition 1
0
1
2
3
4
5
Partition 2
0
1
2
Partition 3
0
1

Producer

Producer uses the topics to send the messages to broker.

Consumer

Consumer receives the messages from broker.

Broker

Broker acts like a middleware component for producer and consumer. If producer sends messages, those messages are maintained in broker. Consumers consume messages from broker.

Using kafka cluster we can create multiple brokers which maintain the messages and load balance. The beauty of Kafka broker is that it can handle many read/writes manipulation without any performance tuning.

The entire Kafka cluster runs in Zookeeper.

What is zookeeper?

Zookeeper is an environment that maintains all Kafka broker and its state. If any Kafka broker is down or not available, Zookeeper is liable to notify Consumer/Producer, so Consumer/Producer will start looking into another available Broker.

System diagram for Kafka messaging system:

Kafka messaging system environment

Kafka messaging system environment

Who are Leaders and Followers?

I have already told that we can create many Kafka brokers in which one Kafka broker is primary broker that handles all manipulation between Producer and Consumer. This Kafka is called as Leader and other Kafka brokers are called as followers. Due to some situation the leader Kafka is down or shut down for any reason, zookeeper selects a new leader from available follower, and notifies to Consumer/Producer about the new Kafka leader. Consumer/Producer starts looking into correct Kafka broker.

Kafka messaging system setup

Download zookeeper from following Apache link

http://www.apache.org/dyn/closer.cgi/zookeeper/

After download go to download folder and open conf folder

zookeeper-3.4.6\conf

You can see zoo_sample.cfg

Copy the this file as zoo.cfg

Open zoo.cfg

Change following property with correct path.

Data Dir=<Your path>

Zookeeper store all data in this path

You have done with Zookeeper configuration and this is a time start zookeeper server.

3

Double click highlighted file(zkServer) to start the zookeeper. You can see following console after starting the Zookeeper successfully.

4

Now we have configured Zookeeper for your Kafka server.

Download Kafka from following apache link

https://www.apache.org/dyn/closer.cgi?path=/kafka/0.9.0.0/kafka_2.11-0.9.0.0.tgz

Extract the Kafka download folder as in below screenshot.

5

Go to bin folder and apply following command to start Kafka server.

kafka-server-start F:\Work\kafka\kafka\kafka_2.11-0.9.0.0\config\server.properties

This command starts your Kafka server.

If you want to stop kafka server, go to kafka_2.11-0.9.0.0\bin\windows and click kafka-server-stop

If you are using Linux, go to kafka_2.11-0.9.0.0\bin\

Now we have kafka server that is ready to start. Once you started the kafka server, you can see following console

Kafka Producer

publicclass MyProducer

{

                publicstaticvoid main(String[] args) throws Exception{

                                Properties props = new Properties();

                                props.put("bootstrap.servers", "localhost:9092");

                                props.put("acks", "all");

                                props.put("retries", 0);

                                props.put("batch.size", 16384);

                                props.put("buffer.memory", 33554432);

                                props.put("key.serializer", "org.apache.kafka.common.serialization.StringSerializer");

                                props.put("value.serializer", "org.apache.kafka.common.serialization.StringSerializer");

                                 Producer<String, String>producer = new KafkaProducer(props);

                                for(inti = 0; i< 5; i++) {

                                                producer.send(new ProducerRecord<String, String>("test-topic", "Test-Key " + (i+1) ,"Test-Value" + (i+1)));

                                                }

                                producer.close();

    }

}

The above code sets necessary configuration for Kafka producer and creates a new topic called “test-topic” which carries the five different messages. This topic message is sent by producer using producer.send method.

Kafka Consumer

publicstaticvoid main(String[] args) {

                //Kafka Consumer configuration

 Properties props = new Properties();

 props.put("bootstrap.servers", "localhost:9092");

 props.put("group.id", "test");

 props.put("enable.auto.commit", "true");

 props.put("auto.commit.interval.ms", "1000");

 props.put("session.timeout.ms", "30000");

 props.put("key.deserializer", "org.apache.kafka.common.serialization.StringDeserializer");

                props.put("value.deserializer", "org.apache.kafka.common.serialization.StringDeserializer");

                      KafkaConsumer<String, String>consumer = new KafkaConsumer(props);

                consumer.subscribe(Arrays.asList("test-topic"));

while(true){

         ConsumerRecords<String, String>records = consumer.poll(100);

                                for (ConsumerRecord<String, String>record : records)

                                                  System.out.println("Partition Offset = " + record.offset() + " Key = " +  record.key() + " Value = " + record.value());

                                  }

}

In the above code sets, the necessary configuration for kafka Consumer and receiving messages from a producer. The Producer carries the messages via topic called “test-topic”.

Boostrap.servers

It will start up all available brokers in the kafka

Group.id

We can set group name for multiple consumer. In our case our consumer belongs to test group.

enable.auto.commit

It will commit the offset value based on auto.commit.interval.ms

session.timeout.ms

Using this timeout we can find out any failures in Kafka server.

Key.deserializer and value.deserializer

This is for internal string serialization process for message data.

Acks

This property is having three possible value which are 0, 1 and all. If set 0, producer doesn’t wait for acknowledgement. If set 1, producer accepts ack from leader, if set all, producer accepts ack from all replica i.e. if your kafka server is having more than 1 broker, it accepts the ack from all (Both leader and follower).

Retries

Number of try for sending messages to Consumer

batch.size

Buffer size for batch size. Let say producer is sending multiple messages to a partition, he will use the batch.size.

buffer.memory

The buffer.memory used by producer for sending messages.

Hope you have understood what Java Messaging System is and why java developers use it. If you have any question, ask from experts and get answered.

Why Hadoop Developers Require Training Sessions?

Hadoop technology is a pack of Opensource features that let developers to store and process big data in a distributed environment throughout computer clusters with the help of simple programming models.

The technology plays vital role in the professional life of those who are working in the IT field. If hadoop developers want to take a step ahead, they need to consider hadoop training.

hadoop training and developmentWhy hadoop? Answers are written below-

Hadoop Tells Latest Updates About Big Data Market                            

Once developers get complete training of hadoop, they are ready to deal with the latest updates coming from the Big Data market. Hadoop let them to store and process large amount of data with economical commodity hardware. Moreover, it acts as an operating system for HDFS- data file system.

Every other person now knows about Big Data after worldwide connectivity and cloud computing. Companies need to pay for the processing power only and they get storage as and when they need. Many challenges are posed by Big Data and Hadoop is a boon to such challenges.

Booming Vacancies In Hadoop Market

ASP.Net Development Platforms Are Dissimilar

Officials have not designed all asp.net platforms equal. Here we will explain key factors that differentiate the platforms that change the way of interacting with CMS for the end user.

We are sharing an overview of these points, adopted from the Aegis Soft tech’s works and opinions. Developers are using asp.net mvc development platform to make a modern approach towards development.

.net platform

  1. Architecture- Tightly Coupled Vs Decoupled

A decoupled architecture can bring you flexibility to design your front-end and leverage your content management potential. In this architecture, content managing application is not equal to content delivering application.

In this situation, the CMS doesn’t dictate the stack, or required the set of technologies to deliver the website and content. Decoupled architecture model delivers content anywhere and in any format.

However, tightly coupled architecture is different and everything ranging from web content, analytics data, customer data, content delivery, and website presentation take place in a single database and app framework.

  1. Development Model – Web Forms Vs MVC

Web forms and MVC are two approaches examined by developers to code your front-end experience.

Asp.net web forms approach is conventional model and Microsoft officials intended web forms to assist developers in getting familiar with client server development swiftly migrate to creating web pages using a visual RAD interface.

The issue with Web Forms is that they support tightly coupled architecture. This explains the app code and the interface cannot be easily recycled.

MVC offers unique architectural pattern to developers. It is a modern approach to asp.net development.

Using MVC, a request can be sent to the Controller which later determines the Model and UI type to put together in order to develop apt front end interface.

You can also make use of Razor in MVC.

  1. Structured Content Vs Blob Content

In the IT world, where everyday new devices and channels are arriving, the content recycling task is absolutely critical. It takes several forms. It could be updating the content on multiple webpages or mobile devices, or for both digital and print.

Blob content is also known as binary large object content. Several CMS platforms are still storing content in blob format. You need a large WYSIWYG editing environment where you do content writing of the page, that includes multimedia, images, and some documents; and everything is stored as a Blob in the database.

Developers can rely on their precision expertise to explore asp.net mvc development platforms.

Differentiate Between Hadoop And Data Warehousing

The hadoop environment has a same aim – to gather maximum interesting data from different systems, in better way. Using such radical approach, programmers can dump all data of interest into a big data store. This is usually HDFS, cloud storage that is good for the task as it’s cheap and flexible. Also, it puts the data close to a reasonable cloud computing power.

You can still rely on ETL and create a data warehouse using tools, such as Hive. You have all of the raw data available with which you can define new queries and perform complex analyses over all of the raw historical data.

Hadoop toolset empowers users with great flexibility and power of analysis as it performs big computation by splitting a task over range of cheap commodity machines that let you to do tasks in more powerful, speculative way that is not possible in conventional warehouse.

A datawarehouse is a structured relational database that is intended for collecting all the interesting data from multiple systems. You need to clean and structure the warehouse when putting data into it. This structuring and cleaning process is known as ETL. The data warehouse approach is effective as it keeps the data organize and simple. Yet this can get very expensive as enterprise data warehouse are usually built on specialized infrastructure that becomes pricey for large datasets.

Hadoop vs Data warehouse

Data warehouse is a database built for analysis. It encompasses a wide range of apps today, from large scale advanced analytical data stores to pre built BI apps. Data warehouses are becoming a mainstay of the IT infrastructure as they enabling both long-term strategic planning and agile responses to present market conditions.

Both big data and data warehousing share same goals, i.e. to bring business value through the data analysis. Big data is in several ways an evolution of data warehousing. Many technologies are using Hadoop and NoSQL databases for big data.

Being the largest database in an IT organization, data warehouse can bring distinct data management challenges than usual OLTP database. Various advantages for running such data warehouses online are-

  • Partitioning
  • Compression
  • Read consistency and online operations
  • Analytics
  • SQL extensions for analytics
  • Advanced analytics and more

To get more updates on hadoop datawarehousing, keep looking for this space in future. For queries, you can make comments in below section and ask experts whatever is confusing you.

How To Protect Your Intellectual Property While Outsourcing Java Development Projects

Intellectual assets or property of a person or a company hold many intangible things that are usually not visible through eyes, but valuable to someone. It includes trade secrets, designs, artistic work, trademarks, copyrights, concepts, company’s data, etc.

Companies encounter heavy competition and thus, they all need to protect their secret data from competitors and other third parties. This is why it is crucial to protect all your intellectual property while planning for outsourcing development project.

The requirement for outsourcing web development is rising with time and especially .net, PHP, and java development outsourcing have emerged as the significant and often outsourced web technologies. Protecting intellectual property is the concern for companies and businesses.

Many times businesses have caught unethical companies that have been misusing the technologies and intellectual property of clients. How the enterprises can protect their secret data and keep it safe forever?

Intellectual property

Here Are Few Tips That Will Help You Out

  • Well documented information security management policy

You must enquire about the information security management policy of a vendor prior providing your project details to them. There is a specific set of rules and regulations that every professional and vendor follows while handling the secret data of their clients. In case you find that the service provider is not taking the policy seriously or there is no policy, then you must look for another IT development firm.

Genuine vendor will provide project development policy and almost every vendor has a system in which every member of the company needs to sign a confidential agreement. You can search such vendor for your project.

  • Never explain the whole project, provide them required information only

This is one of the best ways to lower the risk of confidential property theft. You can set a limit on information you share with company regarding your project.

  • Source code and software ownership

It is important to clarify the ownership of the source code before they start with the project. There are companies and developers who agree to provide complete ownership of the source code and software, but then there are vendors exploit situations where clients don’t make first move towards discussion for the topic.

It hardly matters if your requirement is large or small; you should understand that safety of your data is critical thing that should not be compromised. When you think of hiring java development outsourcing vendor, you should select the one who meets all your requirements and above tips.
