FaaS stands for function as a service. It is the concept of severing less computing that’s why it is known as serverless or serverless architecture. Before this, for deploying apps, developers use PaaS (Platform as a service) but now new cloud computing service is here named as function as a service. Now software developers can take full advantage of FaaS to deploy “Function” as a piece of business logic. Postulates Of Function As A Service: It Completes the quality of dealing with ideas rather than events i.e. abstraction of servers away from the developer. No need to pay extra charges as the user just have to pay the bill based on consumption and execution. Services are derived by events and also scalable. Benefits Of Function As A Service: FaaS Can do voluminous transactions and also isolates and scale them. It can also handle a burstable workload. If the user wants to use this service once a day, month or year then no need to pay for 24/7/365 It schedules all the tasks. One can also run the only piece of code on schedule time. Types Of Functions: There are many areas where we use functions but few of them are listed as follows. Scheduled job or task Process a web request Process queue messages Run Manually These functions also chained together. For instance, a web request could write to a queue which is then picked up by different functions. Providers of Function as a Service AWS, Google Cloud and Microsoft Azure all are the FaaS providers. Many innovations are still in process in this area and changes are rapid and improve its functionality. In a nutshell, function as a service is now a new future of software and application developers and will be widely used. In future. Click Here to read blog on new techology
KOTLIN Kotlin is an open source programming language like Java but kotlin syntac is may not be similar to Java, whereas, internally kotlin is reliant on the existing Java class library to produce wonderful results for the programmers. It is a general purpose, statically types programming language for the JVM and Android and it combines the OOPs (object oriented programming languages) features. Kotlin is developed by JetBrains in 2010 and has been open source since 2012. The main motive behind developing Kotlin is to provide code safety, clarity and interoperability to the developers around the world. Design Pattern of Kotlin Here are many design patterns of Kotlin. We briefly explained that patterns below Singleton Singleton is a first design pattern comes to the mind when we talk about Kotlin patterns. It’s built right into the language. Behold, Object; JustSingleton.value will be now available from anywhere in the package. And it’s not a static initialization. Decorator If we talk about Decorator. We know the one that allows us to add a bit of functionality around some other class. Earlier IntelliJ would generate them for you. But it goes further now. Here is one more thing HashMap that gets excited each time a new key is added?We have by keyword, with the help of this keyword we can define a backing instance in the constructor and delegate all the methods.Note: – If you want to access your own map with square brackets, and have all other methods work as before Factory Method To implement FactoryMethod we have Companion object that will allow us to implement this method in very easy manner. How to initialize an object where you want to control the object. Possibly because it has some covert stuff to do inside. Strategy Last design pattern principle for today is Strategy. This one is super easy because Kotlin has higher order functions. To change behavior at runtime, you should keep a point on mind that it’s indeed a Strategy pattern, and changing signature won’t work. Multiplatform Programming Language It is very explicit goal for Kotlin to work on all platforms, but we see it as a premise to a much more important goal: sharing code between platforms. As I told you that it a multiplatform programming language so it can handle any and all components of a modern application with the help of all other platforms like JVM, Android, JavaScript, Windows, Mac, Linux, iOS and even embedded system. How Kotlin works as Multiplatform Language Well we are using word multiplatform again and again but it does not mean that its mean is compiling all code for all platforms. Yes of course, model has its own limitations, and we know that modern applications need access to unique features of the platforms they are running on. Kotlin does not limit us to the common subset of all APIs in the world. Each component can share codes with others but it can access APIs of platform at anytime through actual or expect mechanism provided by the language.

Software Development Life Cycle Software development life cycle is the process which is used by software developer to build a software. In this process, the following steps that help developers to gather the required information which is important in SDLC. 1. Requirements analysis and gathering In the beginning of any project or software development the very first step is : what the requirements of the client are? The developer first gather his or her requirements that what sort of software do they need? Whether is it feasible or not. If it is possible to build then gather requirements by software developer by using various techniques such as interviewing, group discussions, brain storming etcetera. 2. Building Project Scenario or design After getting all the requirements of client, next step of software development life cycle is making scenario of project in order to start building process of software. As we know the backend plays crucial role in any software development so in this phase of designing the main focus is backend as well as front end. 3. Development phase As move further to the next step of SDLC is development of software. In this phase of software development life cycle the developer choose programming language. Developer can use for the development of software and then develop software as per scenario using algorithms and logics. 4. Testing Phase After developing software using SDLC then developer moves to the testing phase. In this phase of SDLC the tester applies all types of testing on the developed software and check whether the software passes all the alpha, beta testing or not . 5. Deployment Finally, the software is ready as per phases of SDLC and is ready to use. The next step is deployment so that client can use it. 6. Maintenance Maintenance is that step of software development life cycle in which the modifications and changes has been done in order to run software efficiently and it is the responsibility of the software developer to make working of software easy as much as he can. So these are the phases and steps of software development life cycle. Here are some other blogs related to software
What is Python Programming Language? Python programming language is a popular language nowadays. It was created by Guido Van Rossum, and released in 1991. It is used for: Web Development Software Development Mathematics System Scripting What can Python Language do? By using python programming language we can create web applications. Python can be used to create workflows along with other softwares. Python can be used for connecting to database systems. It can also read and modify files. By using python we can handle big data and perform complex mathematics. Python can be used for production-ready software development and prototyping. Why Python? Python can work on various different platforms like windows, Mac, Linux, Raspberry Pi etc. The best thing about python is that it has very simple syntax just like English language thus, making it easy for user. In python, developers to write programs with short syntax than other programming languages. Python runs on an interpreter system, meaning that code can be executed as soon as it is written. This means that prototyping can be very quick. Python can be treated in a procedural way, an object-oriented way or a functional way.

Android Q Release Date Android Q is a latest upcoming version of Android. Finally we got official announcement for releasing date of Android Q is 9 May 2019. Well we should praise XDA-Developers because many of us are waiting for Android Pie and they developed Android Q. This is fantastic, I mean too much brilliance and hard workers they are. Feature Rumors We can say it feature rumors or we can say it, customer’s expectations toward latest version of Android One of the conformed feature of Android Q is it’s gone a be wide dark mode system. This looks classy. This setting can be set to always ON or it can based on the time of day. This feature is developed on it to break the feature of Android Pie because in Android Pie this is only present in certain app or on selected screen Google launched latest version android 10 on some devices for testing. They are trying to add new feature that is desktop mode and a revamp of privacy options. One thing is to notice that this includes totally new approach to permission settings. It means we will have ability to restrict limit an app’s access to a specific setting, such as location, while the app is in use. Another rumor features is screen splitting, which is my personal favorite only developed in Android 10. I mean so excited about it. Screen splitting means you can access two apps together. Screen will divide into two parts and both applications will work together.
Kotlin Vs Java its now become a trendy and hot topic in today’s era.Everyone is familiar with java. So before start blog I would like to explore about Kotlin. Earlier developers used Java for android apps or C/C++. But Few years ago Android officially announced Kotlin as its first supported language. Kotlin History Kotlin introduced in 2011 by JetBrains. The main reason to create kotlin was to make something better than Java in every possible way. Kotlin was made inter-operable with java because JetBrains did not put an effort to write an entire new IDE’s from scratch. Which one is better for Android- Kotlin Vs Java When kotlin released after that every developer started thinking about which one is better for android kotlin or java. So this becomes a huge debate of kotlin vs Java. I will clear some doubts for this I am gone a tell you about features of both (kotlin and java) . JAVA Java is favorite language from the beginning because it is a general purpose programming language and object oriented class based language. Without any doubt java is the most effective and growing programming language ever created. Advantages of Java Platform Independent: This is a main feature of java that it is a platform independent language. It means it has the ability of maneuver simply from one system to a different. Flexible: Java can run in browser window or even virtual machine. You can reuse code and update software in java. Java ensures faster build process than java. Java language is secure It has a potential for a program many tasks at the same time at intervals a program. Disadvantage Of Java It requires more code which can be a reason of errors and bugs. It’s slower in comparison to many other languages and requires a lot of money. Java has limitations that cause problems with Android API design. Kotlin The main motive to develop Kotlin was to add some additional features to Java for handy mobile applications. Kotlin is based on Java virtual machine and kotlin language is a statically and open source language. Kotlin codes can also run on ISO and compile it to JavaScript. You just need to install kotlin plugin and configure it to your project. Advantages of Kotlin Switching from java to kotlin is very easy because you need to just install kotlin plugin. It cost nothing except for learning and training. Possibility of error is lesser than java. Got a lot of traction in Android development, but it’s also being used in backend projects such as Spring 5 Disadvantages of Kotlin Its tricky to find kotlin mentor for a team because kotlin developers are still a rarity. Kotlin is new as compare to java so for kotlin problems it is difficult to find answer. Android compilation tends to run slower in comparison to pure java project. How Can Switch From Java To Kotlin Be Helpful? In Kotlin vs java race everyone want to swtich from java to kotlin because its a modern language and it has many benefits as compare to java Kotlin is newer than java as I mentioned advantaged of Kotlin there are many option available in kotlin which were not available in Java. We can build a project with both java and kotlin codes. Because kotlin is simultaneously operable with java. Kotlin has the majority of Java and frameworks. Kotlin is an enhancement of Java, so a java developer or an existing java application user will be easily able to comprehend what Kotlin cod e is doing. It looks familiar, the code is easy to read and understand.
Google Flutter Brief Description Google Flutter is an open source software development kit which is organized by Google and it is used in Google Fuchsia. Fuchsia is an operating system which is also a Google product. Google Flutter History Flutter’s first version was known as “Sky” and it ran on the Android operating system. It first came in 2015. Flutter’s latest version is Flutter 1.0 and releases on December 4th , 2018. It is a first stable version of the framework. What Is Flutter Google Flutter is a latest and trendy topic by Google to design High performance and High fidelity mobile apps for Android and IOS, using single code base. Well if you are thinking to learn flutter but you afraid from coding languages. If you don’t have coding background. You can easily learn flutter because it uses dart as their primary language to create single code. Dart is also a Google language. Dark is very easy to learn so can make your career in dark language, since most programmers are not already using it. In future everything gone a change. So it can be a great opportunity for all new comers. Some Fabulous Features Of Flutter: Well here are many beautiful feature flutter have but few of them I would like to share with you i.e. Native Performance: Google knows everything and it knows how to be up to date. Google Flutter is cross platform so its widgets can incorporate with all critical platform differences such as icons, navigation and icons to provide full native performance on both Android and IOS. Fast Development It has hot reloading you can say it reloads in milliseconds. It uses fully customization widgets to build native interface in minute. Expressive And Flexible UI Well it focuses on native end user experiences. It gives fast rendering and flexible designs.
IAAS PAAS SAAS: CLOUD COMPUTING IAAS PAAS SAAS are the trendy topics of Cloud computing for small business all over the world. This topic covers most of the online territories. Before switching your business to cloud service for infrastructure deployment or software deployment. You should know about the differences between infrastructure as services (IAAS), software as services (SAAS) and platform as a service (PAAS). These three services are the three main categories of cloud computing. Basically cloud computing is using a network of different servers and these servers have their functionalities like host, store, manage and process date online. INFRASTRUCTURE AS A SERVICE (IAAS) Cloud infrastructure is known as infrastructure as a service (IAAS). This service is completely automated compute and highly scalable. IAAS service is self made service, in this we will have network, storage, servers, and virtualization. That’s pretty nice that this IAAS provides these services. Instead of purchasing hardware outrights, it allows users to purchase resources on demand. What IAAS Delivers Basically IAAS only delivers cloud infrastructure to organizations. It includes servers, networking, and storage through virtualization. These servers provide through API or dashboards to the client. IAAS handle all the servers and storage through virtual data center in the cloud. What’s the drawback of this service? IAAS clients have to implement their own operating system, not only that in fact they have to access middleware, data, runtimes and applications. IAAS users face many problems and in this case too many responsibilities are there. IAAS Advantages And Characteristic IAAS is a most flexible cloud computing model It is highly scalable Resources are available as a service Provides complete control of the infrastructure to organization. PLATFORM AS A SERVICE (PAAS): PAAS or platform as a service is a cloud computing service which provides framework to application or other developers. In this developers can develop or customize the software or applications. It makes the development, testing or deployment of software easy, fast and cost- effective. What PAAS Delivers Delivery is similar as SAAS mode, there is a little difference i.e. it provides the platform to create software or application where as SAAS delivers the software on the internet. Developers can easily develop his software or application in PAAS. It provides all components and developer has not need to take worry about infrastructure, server, software updates or operating system. PAAS Advantages And Characteristics Allows easy migration to the hybrid Greatly reduce the amount of coding Web services and databases are integrated PAAS provides many services to assist with the development, testing and deployment of apps. SOFTWARE AS A SERVICE (SAAS): It is also known as application services. This service is most commonly used for business in cloud computing. SAAS uses web application and these applications are managed by the third party vendor and its interface is accessed on the client’s side. What SAAS Delivers SAAS makes all things easy for clients because it eliminates the installation of operating system and run application on computers. As mentioned in picture that everything will manage by the vendors: application, data, middleware, runtime, operating system and infrastructure. We can say that all the facilities are provided in SAAS. Developers just have to access software or customize according to their needs. SAAS Advantage And Characteristics It reduces the time and money which consumes in installing operating system, hardware, and managing software. It managed from central location It is accessible over the internet It hosted on remote server
Before going forward first I want to tell you concept of AGILE Methodology. So let’s start. What Is Agile Methodology? AGILE methodology is an easiest and best method to develop and test the software as compare to other methods like Spiral Method and Waterfall Method. Here I said easiest and best let’s understand these words in agile method. It means that AGILE Methodology is practice to promote continuous iteration of development and testing. Let’s understand it in deep. AGILE means the ability to responds changes- changes from Requirements, Technology, and People. Here we will talk about Technology which is software development. Before AGILE Methodology we have Iteration and incremental process. In Incremental process development divided into parts but these parts does not work till the completion of whole software. Besides this Iteration process also divides the development but after completion of one part it starts working. But AGILE Methodology is a combination of both Iteration and Incremental process. Clients can interact with their project any time during the process. Clients/Customer involvement is there always. They can interact anytime. Engineering actions are carried out by cross functional team. It means that all the team members will be experts. No one will handle others work that individual experts will handle their own work. Like management team, marketing team, UI expert etc. In this developers and testers work together with the involvement of customer. To make it more simple for you I am gone tell you about other methods so that you can understand it and can compare and relate it with other methods. After all the older methods AGILE come forward in market you can say that it inherit some qualities from other methods. Advantages of Waterfall included in AGILE Simple To Implement: why I am telling simple to implement because it has sprints. Sprint is just like one phase. It divided the work into small sprints. After completion of one sprint (eg: designing, development) you can check the working process of the part. Client and project manager can interact with each other after completion of one sprint. Here is used word Sprint, it means all the task is divided into small parts if one part is complete then it called one sprint. As mention below: Advantages of Protocol Method Included In AGILE Users are actively involved in the development. Same happened in the AGILE Method like if one sprint is complete than project owner or user can access it and check if there is any other requirement or not. Due to involvement of clients or customers errors can be detected in much earlier stage. Missing functionality can be identified easily. Advantages of Spiral Model Included In AGILE In spiral method it divides product in different prototypes. Like if one prototype is completed then client can see the working of that prototype. With the discussion of client errors and corrections can easily do in that stage. Basically AGILE methodology is a combination of waterfall method and spiral method as I said before. How We Can Do Work With Agile Methodology The picture given below explains everything. What customer wants and AGILE Delivers to Customer First of all as I told you before again and again that customer involvement. The owner of that particular product should aware about his product completion stages. Here I used word transparency it means that there should be proper interaction between product owner and developers. So that owner could know that which part is complete and which part is in process. Due to this it will be easy for customer to predict that in how many days his product will ready to work. After that I told you that in AGILE method we work in sprint (small chunks). When one sprint is completed then it should be on working stage. Like if you developed five pages website, in that website if two pages are ready and if product owner can start his site or web application with these two pages then we have to focus on users. AGILE Methodology improves quality of product because in this we have experts for each department. Because we know how many team members we need for one single product we can predict the cost of that product. It allow changes because we divided the product in small sprints if is there any changes required than we can change it in next sprint. This advantage is taken from RAD Method.
