How Cloud Stores Data – When you deploy your HDP cluster on an IaaS cloud, you can take advantage of native integration with the storage services available on each cloud platform: Amazon S3 on AWS, ADLS and WASB on Azure, and GCS on Google Cloud. This integration is through a cloud storage connector with HDP. Its primary function is to help you connect, access and work with data in cloud storage services.
The cloud connector enables you to access and work with data stored in Amazon S3, Azure ADLS and Azure WASB storage services, and Google Cloud Storage, including but not limited to the following use cases:
How Cloud Stores Data
The cloud storage connector is installed as an individual Hadoop model. Libraries and their dependencies are automatically placed on the classpath.
Six Must Have Features When Storing Data In The Cloud
Amazon S3 is an object store. The S3A connector exposes the Hadoop filesystem interface to the AWS Java SDK to access web services, and provides Hadoop applications with a view of the bucket’s file system. Applications can manipulate data stored in Amazon S3 buckets with URLs starting with the s3a:// prefix.
Azure WASB is an object store with a flat name architecture (flat namespace). The WASB connector implements the Hadoop filesystem interface using the WASB Java SDK to access web services, and provides Hadoop applications with a view of the data file. Applications can manipulate data stored in WASB with URLs starting with the wasb:// prefix.
Azure ADLS is a hierarchical file system compatible with WebHDFS. Applications can directly access data in ADLS through the WebHDFS REST API.
Similarly, the ADLS connector implements the Hadoop filesystem interface using the ADLS Java SDK to access web services. Applications can manipulate data stored in ADLS with URLs starting with the adl:// prefix.
Cloud Vs Local Storage
Google Cloud Storage (GCS) is an object store. The GCS connector exposes the Hadoop filesystem interface to the GCS Java SDK to access web services, and provides Hadoop applications with a view of the bucket’s file system. Applications can manipulate data stored in Google Cloud Storage buckets with URLs starting with the gcs:// prefix.
The WASB connector enables reading and writing of block blocks and page blobs from the WASB object store.
The GCS connector supports access to Google Cloud Storage. This feature is a technical preview: Not suitable for production use.
. As a result, when you run FS shell or DistCp commands against HDFS, you can do so without specifying the

To use a cloud storage connector as the file system for HDFS. This is not recommended or endorsed. Instead, when working with data stored in S3, ADLS, WASB, or GCS, use a qualified URL for that connector. Want to access all your digital files on all your devices? Keeping it all in the cloud makes it possible.
Think of it as a storage unit you rent when you have too much stuff in your house, but later realize you can’t put your stuff away forever. This cloud is where you store your data — files, photos, videos, etc. so you don’t clutter up your hard drive.
You are well connected to your internet cloud. When you connect, you can send a copy of your information to the cloud server where your data is stored. When you want to access your information later, you can do so directly from the web or mobile device.
After you put your files in the cloud, they are cheaper than the storage device you visit once a year because you can access those files wherever you have an Internet connection! This includes smartphones, tablets, and computers connected to the Internet anywhere in the world. So not only can you safely store those files and free up your hard drive, you get the added benefit of being able to access those files anywhere, anytime!
Overview Of Cloud Computing: What? Why? And How It Works?
Private cloud services may be available. Some clouds are designed specifically for your photos or email. Others are designed to store entire document folders, and some can hold all of your data! Personally, I try to use the best service for all types of files I want to store, so I use Flickr for photos, Google Docs for files, and Evernote for all my notes.
Is the cloud 100 percent secure? No. When you put your data on the Internet, you must consider that there is at least the possibility that your data will be damaged.
Dropbox reported being hacked in 2012. As a result, they started offering you the option to use so-called “two-factor authentication” to access your account.
Here are some tips to protect your information if you’re just getting started. Number one is to only back up your non-sensitive files until you understand how cloud storage works. If you have sensitive files that you want to send to the public domain, I recommend that you upload these files to your computer before uploading these archived files. I know this is a bit advanced, but it helps to add an extra layer of protection.
Should You Be Storing Your Data On The Cloud?
And always remember to use a strong password to give yourself extra protection! Use uppercase and lowercase letters, numbers, symbols. And don’t use words you find in the dictionary.
I love taking pictures of my family. I take tons of pictures of my son, my husband, my dog, my mom, and more! So how do you manage all these images? I don’t want them taking up valuable space on my phone, so I connect them to my computer. But after a while I have too many pictures on my computer and I start running out of space. So what do I do?
That’s when I turn to cloud storage sites for photos like Flickr. Flickr not only allows me to store and organize all my photos and videos, Flickr also allows me to share these precious memories with my family and friends. Then the people I love can not only see my photos, they can comment or even edit them for me!
Another great thing about Flickr is that I can access my photos and videos not only from my computer, but also from my phone or tablet. Also, I get a lot of storage space for free with Flickr, 1 terabyte. Depending on the size of the photos you download, this can mean you can store anywhere from 230,000 photos to up to nearly a million on Flickr alone!

Another thing you may not know about me is that I love to bake! Or what I really like to do is take traditional recipes and turn them into vegan recipes. Instead of clipping recipes or tagging them, I’ll use a cloud-based service like Evernote.
Evernote is very powerful because it can store photos and images that are useful for doing research. I might see a beautiful cake in the bakery window that I want to copy into my own recipe later. So I take out my phone, take a picture of the cake, and then save that picture in Evernote with a quick note about it. Later, when I’m ready to try the recipe, I can download the picture so I know exactly how I like it.
But Evernote isn’t limited to recipes, what I keep in it is limited by my thoughts to things that inspire me or that I want to remember later. Instead of cutting and pasting text all over the place, I can declutter my life and keep my digital brain in one place.
The general cloud I like to store everything in is Apple’s iCloud. I can back up absolutely everything on any Apple device, and I can access all that data on any Apple device, including iPhone, iPad, and Mac.

The best part is, I can share all my content — songs I make on Garageband, all my photos and videos, Socialcam videos I’ve edited, my current iWork documents and presentations — right there. between all my devices.
One of the things I love about this is that I can access my music anytime on any device. I no longer need to have a separate iPod and smartphone to listen to my music.
