Cloud storage & Cloud Computing: All you need to know

Cloud computing has revolutionized the way we do everything. We keep our photos, music files, and other important documents on Cloud storage systems that are globally distributed for easy access anywhere in the world! Cloud computing is a system of storing data on the internet. Instead of storing your files in one place, like on an internal hard drive or external USB memory device (which can be risky), you upload them to cloud storage where they’re safe from physical damage and hackers with access to other parts of their network who might want what’s inside- like međŸ˜‚.

Post updated on November, 2021

The main benefits are convenience: anytime anywhere there’s quick accessibility; cost-effectiveness because most providers offer monthly plans at low rates when compared against traditional solutions per GB capacity. It also allows users more freedom over how much information is being stored by letting them choose between free accounts that have very little amounts available but allow unlimited reads/writes every day.

By 2025, cloud storage will have surpassed 100 zettabytes. To put this into context, a zettabyte is equal to one billion terabytes (or a trillion gigabytes), Doesn’t it sound massive amount of data Right ?đŸ¤”

On the same year, worldwide data storage will surpass 200 zettabytes, with around half of it being kept in the cloud. In 2015, just 25% of all computing data was kept in this manner.

Numerous cloud computing storage providers including Nihao Cloud provide various services that can be useful to the customer to a greater or lesser extent. This post will not be about our service at NiHao Cloud and I don’t have a favorite in this category since they’re all unique in their ways. Nevertheless, each cloud computing service has a few common words, which I have discussed below.

Best Cloud Storage Providers

Cloud Storage Services: 

While hosting firms often provide various services, the primary one is data storage on the “cloud.” we will discuss some of the terms with respect to storage below:

Synchronization

Synchronization of files implies that whatever you save to the cloud on one device will be available on all of your other devices. Whether it’s movies, pictures, documents, or music, the cloud can save everything. Most hosting providers have already adopted this since it is the entire core of cloud computing storage. At work, upload your data and then access it when you get home. Additionally, they offer a desktop version that resembles an illusory drive on which you may save your data. It’s much more convenient to utilize the desktop version than repeated login into your account on your browser. It looked like such an intriguing method to save your info. 

Backup

While cloud storage needs you to store your data online actively, the backup function provides an alternative. It enables the smooth transfer of your data to the cloud for safekeeping. This is very useful if your hard disc fails or you lose your smartphone/notebook. Another method to accomplish this is to download backup apps to your mobile device, often already offered by cloud computing storage providers. You may select to save your pictures in your backup folder, erasing the photos stored on your phone in the process.

Numerous cloud storage providers do not even have a backup option. On the other hand, there are also plenty of them that are only for file backup.

File sharing:

The feature is self-explanatory. Are you collaborating with your mates on a class project or a task? Utilize numerous methods for sharing your files. You may either connect your folders or generate download links that you can share with your friends. This is probably one of the things that your physical storage lacks. To be quite candid, I can’t imagine functioning without cloud computing storage. Not to mention the hundreds of millions of individual users, but we’ll get to that later.

Versioning of objects:

Cloud storage enables this functionality. Once enabled, a history of file changes will maintain for all objects. This allows you to recover previous versions of your files or even recover erased data. Each item is endowed with specific characteristics that aid in its recognition. When you remove an item enabled for this feature, a duplicate of the object is immediately stored with attributes that help identify it. I suppose I should say that not all service providers provide this option in their free plans. Additionally, some do not include it in their payment plans.

File retrieval:

It’s comparable to object versioning. Some/most cloud services provided by default or via the installation of different add-ons can recover lost data. Some have a temporal restriction on how long data may be recovered, while others keep it forever. They are often kept in a subdirectory called “trash” or “deleted files.” If you are unable to locate it, it is most likely not included in your current plan. You may contact me, and I will gladly assist you by studying for you or just giving the knowledge direct from my brain. Additionally, you may consult my reviews section for additional information. Here is an example.

Third-party applications:

The box is an example of this. It integrates third-party applications such as Microsoft Word, PowerPoint, Google Documents, and Google Sheets within the software itself. It’s one factor to consider while choosing a cloud storage provider. Few cloud services integrate third-party apps.

Cloud Storage Service Types

Not all cloud storage users have the exact needs or requirements. As a result, many cloud storage providers provide a variety of distinct cloud storage solutions.

Personal

Personal Cloud Storage While most cloud storage services let you access their remote servers, you may also set up your server at home to establish your cloud storage.

Western Digital My Cloud, for example, enables you to create a private server accessible only to you. There are a variety of reasons why this may be necessary. It’s ideal for streaming media — such as music and movies — inside your house since you can depend on your home network’s better speeds than you would receive streaming from a server over the internet.

It also means you won’t have to worry about your cloud vendor sniffing around and analyzing your files if your media material comes from less-than-trustworthy sources.

Private cloud storage, on the other hand, is essentially business-specific cloud storage. This is the process through which a company establishes its storage servers in-house.

There are various reasons why a company may want to create its private cloud storage, but one of the most compelling is that some companies are legally obliged to keep customer data on-premises.

Public

This is often understood when the term “cloud storage” is used. Google Drive and pCloud, for example, have whole racks of servers devoted to serving the public in data centers, enabling customers to keep their files in the cloud.

While these providers primarily serve the consumer data storage market, several cloud storage providers also provide business-oriented solutions for off-site data storage. In addition, check out our roundup of the top corporate cloud storage services.

Hybrid Storage

Combine the speed and security of private cloud storage with the simplicity and adaptability of public cloud storage, and you’ve found hybrid cloud storage, a novel approach to online file storage.

Hybrid cloud storage also enables you to mix your on-premises storage with that provided by a public cloud storage provider. This allows you to choose to store data locally and files remotely in the cloud.

This combines the best of both worlds and may be the optimal option for a wide variety of companies. As explained in our previous Microsoft Azure review, services like Microsoft Azure enable you to manage your hybrid cloud storage.

Picking the SQL Database For You

A Comparison of SQL Database Flavors: How To Pick The Right SQL Database Flavor For You?

SQL, or Structured Query Language, is a database that has widespread uses with many flavors– which we will explore. As such, in our data-driven world, SQL is fast becoming an essential skill. Therefore, in this article, we will look at the most popular flavors of SQL databases individually and then compare the database flavors together. In addition, we’ll help you figure out the right choice for you; in case you want to learn more about some key basic fundamental query building structure– CRUD Operations.

Two Types: SQL vs NoSQL

There are two main types of databases: SQL and NoSQL. Before we begin, it’s important to know the differences between the two.

While SQL is a relational database that employs a table-based structure, NoSQL is a non-relational database that employs a variety of data models for accessing, retrieving and modifying database. Moreover, SQL has a predefined database schema, whereas NoSQL has a dynamically defined schema.

Additionally, the most popular flavors are mainly based on SQL rather than NoSQL— only MongoDB makes the cut in the top 5 databases in 2021—with other examples like Elastisearch, DynamoDB not used as often by developers. MongoDB is so popular because of the flexibility in offers in database design and the high performance it delivers.

The Most Popular SQL Database Flavors in 2021:

  • MySQL
  • PostgreSQL
  • Microsoft SQL Server
  • SQLite
  • MongoDB

Moreover, the Stack Overflow Developer Survey 2020 has placed MySQL as the most popular database:

PostgreSQL, or commonly known as Postgres, is also an open source object-based relational database management system (RDBMS) initially released in 1996. Moreover, its queries are natively run on pgAdmin, its client. In addition, PostgreSQL is a great database language for beginners because of its broad applicability.

Key Features & Advantages of PostgreSQL:

PostgreSQL focuses on SQL compliance; in other words, it is growing into one of the most popular flavor of SQL in recent years:

  • Client-server model architecture
  • Offers geo-location queries
  • Data integrity
  • Support for JSON data types

After that, let’s take a look at some advantages now:

  • Larger data storage for databases
  • Multi-version concurrency control (MVCC) without read locks
  • Creates views that are updatable
  • Creation of user-defined functions, triggers, data types, etc.
  • Runs on all operating systems: Windows, Mac, Linux, etc.
  • Robust and powerful
  • Huge community support
  • Compatible with many programming languages like C, Python, etc.

Disadvantages of PostgreSQL:

Despite all these advantages and features, Postgres, like any other language, also has its own disadvantages. Therefore, let’s take a look at some below:

  • PostgreSQL struggles in performance factors
  • It is responsible for more memory utilization of computer
  • Data replication is hard

Microsoft SQL Server

Microsoft SQL Server, or MS SQL, is a relational database management system developed by Microsoft in May 1989. Similarly, its queries are natively run on SQL Service Management System (SSMS). In addition, SQL Server is an important part of the Microsoft Data and Business Intelligence platforms.

Key Features & Advantages of MS SQL:

MS SQL is a language that’s growing in userbase with its widespread use. MS SQL is used by companies like Dell, Yahoo, etc. Therefore, let’s look at some key features:

  • Data compression
  • MS SQL is highly secure

  • It offers different versions to suit personalized needs

Consequently, MS SQL is one of the most popular database languages today, so it makes sense to see some of its key advantages:

  • Free for developers
  • Useful online documentation
  • Debugging tools on SMSS
  • Great community support
  • Highly secure
  • Easy installation with automatic upgrades
  • Easy maintenance

Disadvantages of MS SQL:

In the end, there is no database language that is perfect. Therefore, let’s explore some disadvantages of MS SQL. In other words, like any other database, MS SQL also has negative factors that may affect your choice:

  • Performance tuning is hard
  • There can be a bit of learning curve
  • May be overwhelmed with the huge number of features offered alongside

SQLite

SQLite is a RDBMS built in C library with its primary use being in mobile applications. Unlike other databases. it is not based on client-server architecture, but rather makes use of the embedded architecture.

Key Features & Advantages of SQLite:

SQLite is gaining popularity for its features, customer service and quality. Let’s see its key features in the list below:

  • Configuration doesn’t exist– no installation required
  • Has an easy to use API

SQLite has a lot of advantages that we will look at now. Let’s see what these benefits are below:

  • Runs on multiple OS: Windows, Linux, Mac OS etc.
  • Installation not required
  • Server-less database
  • Flexible and fast database
  • Uses less amount of memory on runtime

Disadvantages of SQLite:

In the end, SQLite has the following disadvantages that we will look at now:

  • Performance compromised because of file system configuration
  • Write operations are recorded
  • Database file size is smaller (15MB)

MongoDB

MongoDB is a document-based database, unlike all the others on this list. As a result, it uses JSON-documents for storing data instead of tables. In addition, you can start writing query from its official editor available at this link.

Key Features & Advantages of MongoDB:

MongoDB is the most popular non-relational database because of these features:

  • Data stored in JSON-documents
  • Indexing used for traversal
  • Horizontally scalable database

In addition, the following are its advantages:

  • Flexible database schema, dynamically defined
  • High speed of access time
  • Easy to setup environment

Disadvantages of MongoDB:

After that, let’s look at some disadvantages:

  • JOINS not allowed
  • Data size is limited in MongoDB

The Right SQL Database Flavor For You Is…

In fairness, it’s difficult to choose one database generically, since each database serves a goal or purpose.

SELECT e.emp_name, AVG(s. salary) AS average_salary
FROM employees AS e
LEFT JOIN salary AS s
ON e.emp_id = s.empid
WHERE e.city = 'USA'
GROUP BY e.emp_name
ORDER BY s.salary;

For instance, this code example above shows that the syntax is actually quite similar. However, it can be seen because the query output is same for MySQL, PostgreSQL and SQLite, there is not much syntactical differences.

However, Microsoft SQL Server is the one that consists of the most differences between all of them.

In other words, the right database for me may not necessarily fit or be the right one for you. As a result, each database is optimized for a specific purpose or need. Therefore, how do you know which database fits for you?

Above all, which database can you learn or base your backend in?
Then, let’s explore some key factors in helping you determine the right SQL database flavor for your needs.

Speed Of Databases:

  • MySQL is fast for concurrent activities
  • PostgreSQL is quite fast
  • Microsoft SQL Server is slower
  • SQLite is fast but not the fastest as compared to others
  • MongoDB is extremely fast for data retrieval since it uses indices to traverse

Performance Of Databases:

  • MySQL has limited performance optimization
  • PostgreSQL is responsible for high performance database
  • Microsoft SQL Server offers high performance and data compression
  • SQLite runs smoothly
  • MongoDB has a great performance because it relies on jsons

Database Sizes Of Databases:

  • MySQL supports limited size database in some scenarios.
  • PostgreSQL supports large database
  • Microsoft SQL Server supports large databases
  • SQLite supports big databases, but with limited file size
  • MongoDB supports large databases

Eventually, you need to ask yourself what factors matter most in your needs before you can aptly choose.

Which Database Should You Choose?

If you’re looking for a fast, high performance database that will be easy to use, MySQL may be the right choice. But, if you’re working on a much larger database or complex queries— PostgreSQL may be the right choice for you.

On the other hand, if you are working with highly sensitive data, then the security, integrity and sturdiness of Microsoft SQL Server may be the perfect choice for your needs. Similarly, if you want fast, portable, and reliable database that runs on multiple operating systems, SQLite may be great.

Furthermore, if your business and data requirements are evolving over time and you need to scale accordingly, the document-based database, MongoDB could be a wonderful selection.

Conclusion to Comparison of SQL Flavors:

SQL consists of multiple flavors of databases used around the world with varying popularity. In addition, these flavors of databases carry plenty of similar traits and syntactically are akin.

Similarly, we proceeded to look at the top 5 databases in the world today individually and then compared the results together; it’s hard to pick one generically since each database serves a goal or purpose.
