AWS S3(simple storage service) is similar to Storage disks or External disks but it is web-based Cloud storage. It is an infrastructure, which is a service solution where we can store files. AWS S3 is working bucket concepts where we can add multiple buckets and upload files in buckets. But these files will be treated as Objects, not as files. We can virtually store any kind of data in any format. We can upload/store unlimited data or number of objects. Individual Amazon S3 objects can range in term of size from a minimum of 0 bytes to a maximum of 5 terabytes. It means we can upload a file whose size can be 0 bytes to 5 terabytes. The largest object to be uploaded can be of 5 gigabytes. AWS S3 stores objects in key-value pair concept, it is like an associate array in terms of programming. It means whenever we upload objects, we need to provide a unique key to store that object. That key can be any string and later this key can be used to retrieve the data. AWS S3 also pr...

Well, the IT industry is more focusing on Automation. IT companies are working on different tools to make the processes like 1. Continuous integration of features 2. Deployment of app code to the server. 3. Model & Provision the infrastructure. 4. Testing application and generate reports etc. Automated. For the above processes, the IT industry is using different tools. Git is one of them. Basically, Git is the version-controlling system which provides the ability to track the changes of files. Version-controlling means different versions of application or files like version 1, version 1.1.   and so on. So you can manage different data sets and if you need the previous version of the dataset, you can get it easily with the help of version-controlling system and you can share your data with anyone. IT industry is using Git as Source code management system in the software development process where developer shares his code or collaborate with his team me...

Tech giants like Google, Amazon, Microsoft etc are continuously working on the cloud computing platform and providing various services to users to make their job easy. If we talk about launching a web application on our own datacenter, we know that pain. Because we need to set up various tasks to launch a web application like: 1. Set up the VM. 2. Install server OS. 3. Set up the inbound and outbound rules 4. Users creation 5. Install the web server/application server and database server 6. Configure the web server and database server 7. Provide access to user 8. Deploy these web application code to server etc It will take time to complete all above tasks, which can be 4 to 5 hours or if we take hosting, it may take 24 – 48 hours to launch our app and it may cost high as per requirements or resources. But these tasks can be done in a short time through Orchestration tools of cloud companies. Let’s talk about AWS orchestration service: AWS Cloudformation. A...

Whenever we do a job/task in Personal or Professional life where we need to do 2 to 4 things to complete that job, lets say if we do gardening, for that we need to perform some tasks like: Sweep Patio and Sidewalk Check for Weeds Cultivate some Soil Mulch some Soil Water some Plants that Need It Fertilize any Shrubs and Trees that Need Fertilizing Prune any Shrubs and Trees that Need Shaping Obviously, It takes time!. But If there is someone who can do these things like a robot then we can save our time & hard work & spend that time in some other tasks. It will be like a gift to us & we will be super happy. In the same way, AWS gave a gift to IT professionals in form of Cloudformation.   Now the question is how Cloudformation is a gift for AWS IT professionals ? Let assume that there is a scenario where we need to launch a mid-level web application, which has the following requirements: 2 instances with 4 GB RAM ...

Cloud migration is now a trend in IT and AWS is becoming the first choice of Companies. Organizations started trusting AWS for cloud services from all kind including IT, healthcare, finance as well as medical. Let us understand why AWS is becoming the first choice of various companies. Pricing AWS follows the “a la carte” approach, which means you pay what you use. This makes a lot of sense otherwise if we go with third-party hosting, we also need to pay for those things which we do not even use. AWS is providing almost 1430+ services in the cloud market on very cost effective mode. The Free Tier AWS does not provide hosting like traditional hosting companies. EC2 service(the backbone of AWS) provides the free credit to run your small web application with micro instance 24/7. Because of this, IT professionals are leery of using EC2 (or the rest of the AWS suite). EC2 is designed to bring web applications online & offline very quickly as per our need....
