Software Development Life Cycle (SDLC) – Phases Involved

Software development life cycle is a process which cannot be taken all at once; there are varied phases involved that are addressed by the developer. All these phases are important for the owners of a software company, who want to keep a tab on the progress of software they want to get developed. The software development professionals touch base with 6 major phases before actually come up with application featuring the pre-stated specifications.

Software DevelopmentThe entire cycle comprises well-thought steps and procedures, starting from its inception till its implementation. The process is implemented on different numerous types of SDLC models namely Waterfall and Agile as per the requirements.

Below listed are the key phases involved in SDLC:

Requirement Gathering and Analysis

As the name indicates, it is the phase in which developers carry out detailed research with clients to know and record their requirements. The first stage of SDLC model, it is also known as the brainstorming phase and comprises numerous sub-stages encompassing Feasibility Analysis. Such analysis is done to check the possibility as how much the idea is probable to put into action.

The requirements and scope varies in case any existing software is being modified. Herein, a detailed study is carried out to understand the underlying problem persistent in the software which is then sorted out followed by discovering ways to solve it. On the contrary, if software is being developed from the scratch, then each aspect is considered in detail before it is committed to be put into action. Developers then carry out maximum research after taking the inputs from the end customer.

Software DevelopmentSystem Analysis

This is defined as the second phase of SDLC in which the entire process is mentioned in detail. It involves drafting a detailed blueprint encompassing a list of procedures. If the entire process looks complicated, the system can also be divided into smaller parts to make it more understandable and easier for developers, testers, designers, project managers and other professionals who will take up the work in the later stages.

System Design:

This is the third stage, wherein developers take into account the blueprint and a logical design is made System Analysts. In this phase, the analysts and designers work in collaboration and use certain tools to create the design with the desirable output.

Coding

Once the design is developed, the software developers take up the challenging task of coding with precision. Each application development company has a specific set of professionals working in this domain as this job requires high attention to detail and is prone to record major number of mistakes.

Often, it is sub-divided into parts, where each developer handles specific part of the work after assessing his/her skill(s). It is a more strategic way to complete the coding job efficiently.

Testing

No application is passed onto the customers for evaluation or approval until it is tested thoroughly. Once the software is ready, it is allotted to the specific testing department where a series of Quality Analysts tests are conducted on the application. Herein, different errors are spotted and done away with the help of varied test cases. These applications are tested in two ways, either manually or using automated testing tools in order to ascertain that every component works fine. Once QA certifies that the software is free of errors, it reaches the next stage for implementation.

Implementation:

Final stage of any SDLC, software is made to run on various systems by real time users to check the performance. Once its performance is trusted to be smooth, it is sent for implementation.

How to Find a Cheap SSD VPS

VPS’s are important when it comes to the developmental process pertaining to desktop computer applications and such, especially when you’re trying to create a business. VPS’s will allow you to operate the entirety of your developmental business through online means, and you don’t even have to physically be in the datacenter to make use of all of your equipment. This is why a VPS that you can rely on is going to be so important for your developmental endeavours, because handling everything quicker and with more efficiently is beneficial for many different reasons. Since a VPS can really work wonders when it comes to how you go about handling your job there’s an obvious reason as to why you would upgrade it, which is where SSD’s (Solid-State Drives) come in. A traditional VPS makes use of either HDD’s or some other type of data storage system, but the difference between an HDD and an SSD are gigantic.

SSD’s are automatically pricier than HDD’s because they have a lot more to offer, so it’s only reasonable that they charge a bit more money to the consumer in order to still turn a profit. You might think that whatever you’re storing your VPS data on isn’t that critical, but it’s one of the most important parts of the entire cog known as a VPS. If you can’t read and write your files at a higher rate of speed your jobs are going to lag behind, and if you can get the job done quicker with the same amount of quality why not give it a shot? We all know that SSD’s are better because they’re quiet, they don’t give off any heat and there are no moving components inside of them (meaning they won’t break as easily as a traditional storage drive would), but how are you supposed to find a SSD VPS that’s both affordable and reliable?

The Search

The search itself might take a little bit of time, and in some cases it might not even take that long, so understand that you’re going to have to use a little bit of brainpower here. The amount of companies out there that are providing reliable SSD VPS’s is pretty intense when you first get into the search, since there’s so many different options it can all become increasingly overwhelming. In order to keep your eyes on the prize you have to sustain the amount of focus you’re putting towards the search, falling for the many dubious discounts and deals that get removed during the checkout process from shady VPS suppliers is something we could do without. Most of the best VPS companies are going to have a relatively high ranking when it comes to SERP (Search Engine Results Page), so a quick Google search should open your eyes to many different SSD VPS providers that can get the job done right.

It might sound blatantly obvious, but use the internet to your advantage. Grab a piece of paper and a pen and start writing down the different rates and benefits each Cheap SSD VPS is going to provide to you, and from there you can pick away at the list until there are two finalists left. From there you can figure out what else you’d like out of your SSD VPS, as well as what kind of developing you’re going to be doing with it. A proper price is going to vary, some VPS’s are going to have a lot more behind them storage space and technology wise than others will, so an average price is really tough to put your finger on. The best thing you can do is try to find the lowest price out there, and then after that find the highest price. This will give you an idea as to which VPS could be considered “expensive” and which ones could be considered “financially efficient”, from there all you’ll need to do is find the perfect balance.

SSD VPS’s are life-changing pieces of technology, and we’re not over exaggerating when we say that. It helps developers’ handle the workload they’re given at a speedy pace, and speed is a virtue that any system administrator won’t take for granted. The mystery surrounding the efficiency of SSD’s is crystal clear as of today, well, for you at least! Take this knowledge and pass it onto your peers, you never know how useful they’ll find it.

Learning about Windows VPS’s

A VPS (virtual private server) is something that most technologically-prone people are aware of these days, and they’re the roots of most cloud-based services today. Whether you’re trying to start up an e-commerce site or simply want a way to effectively manage your content, a VPS is going to make every single job you have to do easier. When you’re using the servers that your initial hosting plan (when you buy a domain you’re usually gifted with a regular hosting plan as well) give to you, you’ll notice that you aren’t getting the speeds that you would really like. Having a personal Windows VPS is a great way to ensure that you’ll receive absolutely all of the attention when it comes to powering your website, whereas the regular means of hosting would have you competing with all of the other clients for hardware resources. A physical server is where the VPS originates, but a VPS is able to be used without physically being there. You don’t need to sacrifice speed when you’re working with the web, the average consumer online is going to want everything as quickly as possible (and it’s up to you to make sure that they get it).

A Windows VPS may not seem like a crucial component right now, but when you look deeper into the issues that they tackle you start to realize something; they actually might be good for something after all (as if it wasn’t obvious before!). There’s no better feeling than being able to say that you’ve got complete control over the hardware resources within your physical server, and a Windows VPS gives you the right to say exactly that. The perfect example of this would be a physical server that is fitted with 64 GB of RAM, and to add onto that there are 8 different CPU’s and about 400-ish GB of hard drive space. This is a set-up that could power even the neediest of webpages and developmental stages, but the point to look at here would be splitting the entire server up into sections.

Each VPS would make use of one specific section of the physical server, so instead of one large server being dedicated to one task they split all of it up to cover more ground. Four people would be able to make use of 16 GB of RAM, 2 CPU’s and 100 GB of space for their hard drives, which is a pretty hearty Windows VPS (although they don’t incorporate any SSD’s, which is another thing you need to look out for!). The components that make up the physical server are going to decide how powerful your VPS is, and when you have your very own VPS you can get into many different mediums. The slowing down of your website can be attributed to the sharing of physical servers with hosting companies, so those who need to have the speediest site they can possibly have need to check out Windows VPS’s.

The concept might seem a bit foreign and strange at first, but it’s for the benefit of everybody. You can completely control your server, that means you get to decide what kinds of software and files you want to have on it (amongst many other things). If you’re an application developer there’s no other way of going about your job in a professional manner, if you’ve got multiple clients that you need to showcase a demo to VPS’s can come in handy. Give the clients your servers credentials and they should be able to pull up the WIP (work in progress) for themselves, and from there they can tell you what they like (or even didn’t like) about the project at hand. It’s much more time-conscious than having to bring the application to the client in a physical manner, and if you want them to be able to connect to your server with ease and relatively quickly you’ll need Windows VPS hosting.

The hardware is an entirely different venture in itself, and that’s mainly attributed to the fact that a server is only as good as the hardware it’s using. There are bad VPS suppliers out there that don’t care about the physical aspect of things, they think that they can just set it up once and the money will roll in for the rest of their lives. The physical server needs a worthy system administrator that’s going to improve upon it consistently, or else you’ll just find yourself dealing with the same VPS related problems over and over again.
