Azure - Migration of legacy .NET applications to Azure

Modern web applications must meet higher utilizer prospects and more preponderant demands than ever afore. By migrating legacy .NET applications to Azure, organizations can ascertain their apps are incredibly secure, flexible and available from anywhere in the world, and scalable to meet spikes in demand.


Migration Process

For example, a global online business needs to modernize its subsisting .NET application due to changes in customer demand. They can migrate their web and mobile application to the cloud for incremented efficiency, legerity, and scale, as well as abbreviated costs. Here, we show a proposed architecture: a plenarily managed platform for building, deploying, and scaling your web apps with Azure App Service and Azure SQL Database.

For the data tier of the app, they can choose Azure SQL Database for its dynamic scalability, built-in perspicacity optimization, and global scalability and availability. They can choose Azure Database Migration Service to migrate their on-premises database to Azure SQL. For the app tier, they can choose Azure App Service, a PaaS service that enables them to deploy the app with just a few configuration changes utilizing Visual Studio. They can choose to deploy two web apps, one for the customer-facing front-end website, and the other a WCF (Windows Communication Framework) or REST services app that verbalizes with both the front-end app and the database and processes business logic. The below describes the migration process.
  1. Provision of an Azure SQL Database instance in Azure. After the app website is migrated to Azure, the WCF/REST services app will point to this instance.
  2. Assess the database utilizing Data Migration Assistant and migrate it utilizing the Database Migration Service.
  3. Provision of the two web apps.
  4. Set up Azure DevOps: engender an incipient Azure DevOps project, and import GitHub repo.
  5. Configure connection strings so that the web tier web app, the WCF/REST services web app, and the SQL instance can communicate.
  6. Set up build and release pipelines to engender the app, and deploy to two separate web apps.

Components

Azure Web Apps offering web applications hosting. It allows developers to focus on delivering business values rather than consuming time on Sever updates or OS patches. Applications built on Java, .NET, PHP, Python, or Node.js can additionally be deployed on web apps.

Azure SQL Database is a plenarily-managed database service, which designates that Microsoft operates SQL Server for us and ascertains its availability and performance. SQL Database additionally includes innovative features to enhance our business continuity, such as built-in high availability.

Azure DevOps provides developer services to support teams to plan work, collaborate on code development, and build and deploy applications.

Service enables seamless migration from multiple database sources to Azure, with minimal downtime.

Learn Java 8 streams with an example - print odd/even numbers from Array and List

Example 1: Java 8 program to print odd numbers from a List   import java.util.Arrays; import java.util.List; import java.util.stream.Collectors; /*Java 8 Program to find Odd Numbers from a List*/ public class DriverClass { public static void main( String [] args) { List < Integer > numbers = Arrays. asList( 1 , 4 , 8 , 40 , 11 , 22 , 33 , 99 ); List < Integer > oddNumbers = numbers.stream(). filter(o -> o % 2 != 0 ). collect(Collectors.toList()); System.out.println(oddNumbers); } } 1. Initialize List using Arrays.asList() method. Java's built-in Arrays.asList() method converts an array into a list. This method takes an array as an argument and returns a List object. 2.  Java List interface provides stream() method which returns a sequential Stream with list of Integer as its source. 3. The Java stream filter() method allow

Java Stream API - How to convert List of objects to another List of objects using Java streams?

Image
In this section, we will show you how to convert a List of objects to another List of objects in Java using the Java streams map(). The ‘map’ method maps each element to its corresponding result. Java Stream API   The Java Stream API provides a functional programming approach over the object oriented capabilities of Java. It is used for processing collections of objects. The Stream in Java can be defined as a sequence of elements from a source List, Set or Array. Most of the stream operations return a Stream. This avails engender a chain of stream operations(stream pipe-lining). The streams withal support the aggregate or terminal operations on the elements. for example, finding the sum or maximum element or finding the average etc...Stream operations can either be executed sequentially or parallel. when performed parallelly, it is called a parallel stream.   Stream map() Method   The Java 8 Stream map() is an intermediate operation. It converts Stream<obj1> to Stream<obj2>

Top 5 Java ORM tools - 2024

Image
  The term ORM refers to object-relational mapping, which uses objects to adapt programming languages to database systems while allowing them to function with SQL and object-oriented programming ideas. Any kind of database management system that can accomplish object mapping to the table in the virtual system is suitable for the implementation of ORM. Java has a wide variety of ORM tools, some of which are mentioned below: 1. Hibernate Hibernate is a lightweight, open-source, non-invasive Java ORM (Object-Relational Mapping) framework that allows developers to create objects that function independently of database software and create persistence logic in any Java or JavaEE application. It offers an abstraction layer, so developers don't have to bother about implementations; Hibernate handles these tasks internally, such as connecting to databases and creating queries to carry out CRUD operations, among other things. Persistence logic development is done with it. Persistence logic r

Java - Blowfish Encryption and decryption Example

Image
Blowfish is an encryption method developed by Bruce Schneier in 1993 as an alternative to the DES encryption method. It is significantly faster than DES and provides good encryption speed, although no effective cryptanalysis technique has been found to date. It is one of the first secure block ciphers that is not protected by any patents and is therefore freely available for anyone to use. This is a symmetric block cipher algorithm. Block size: 64 bits Key size: variable size from 32 to 448 bits number of subsections: 18 [P-array] number of rounds: 16 number of substitution blocks: 4 [each with 512 records of 32 bits each] develop  Example 1: Encryption and decryption using Blowfish import java.io.UnsupportedEncodingException; import java.nio.charset.Charset; import java.security.InvalidKeyException; import java.security.NoSuchAlgorithmException; import java.util.Base64; import javax.crypto.BadPaddingException; import javax.crypto.Cipher; import javax.crypto.IllegalBlockSizeExc
