Google Cloud MYSQL Database Option Explained

Choosing the precise database for your operation isn’t simple. The choice based on heavily on your usage case — in- memory database, logical processing and transnational processing and so on — but it also based on different factors.

In the above article we will covers the distinct database options accessible within Google Cloud across relational (SQL) and non-relational (NoSQL) databases and describe which utilize cases are best fit for every database alternative.

Relational Databases

Data in relational databases is kept in tables, rows, and columns. It is most effective with structured data. They are utilized for applications where the structure of data is not frequently altered. SQL is used for interactions with the majority of relational databases. They provide ACID consistent mode to data which is

  • Atomic: All operations within the transaction are successful either return.
  • Consistent: When you have completed the execution of the transaction, the database is solid in structure.
  • Isolated: The transactions don’t compete with each other. The database controls access to data with content to ensure that transactions appear sequentially.
  • Durable: The results of implementing a transaction remain in place even in the event of failures.


Due to these characteristics are utilized for applications that require high precision and transactions like retail and financial transactions. For instance, when a client orders to transfer funds in banking, you must ensure that the transfer is feasible and occurs on the most current account balance.

In the case of an error or an error in the submission process is likely to be acceptable. The three relational databases that are available in Google Cloud include Cloud SQL, Cloud Spanner as well as Bare Metal Solution.

Cloud SQL: Manages SQL Server, PostgreSQL, and  MySQL databases on Google Cloud. It lowers the cost of maintenance and streamlines the process of provisioning for databases, the management of storage capacity, backup ups, out-of-the-box high availability, and disaster recovery/failover.

It is the best choice for general-purpose web frameworks, such as CRMs, ERP, SaaS, and eCommerce applications.

Cloud Spanner: It is an highly-consistent database and enterprise-class distributed globally offering up to 99.999 percent availability. It was specifically created to bring together the benefits of a relational database structure and the horizontal dimension of non-relational.

It is a database that blends ACID transactions, SQL questions, the relational design and can scale you usually associate to non-relational and NoSQL databases.

Therefore, Spanner is ideal for games payments, payment solutions, global financial ledgers, inventory management, and retail banking, which require the ability to scale infinitely, with high availability and consistent performance.

Bare Metal Solution: It is a hardware solution that allows you to run specific workloads with minimal latency Google Cloud. It is especially useful if you have an Oracle database that you would like to transfer to Google Cloud. It will allow data center retirements and open an avenue to modernize older applications.

Non-Relational Databases

Non-relational databases (or NoSQL databases) store massive, unstructured data in non-tabular formats like documents.  NoSQL databases (Non- relational database )  keep huge, unstructured information in non-tabular formats such as documents.


These types of databases are typically employed when large amounts of diverse and complex data have to be organized, or their structure is continuously changing to accommodate new business demands.

They are more efficient than relational databases because queries don’t need to go through multiple tables to provide an answer. It makes them perfect for information subject to change or applications dealing with diverse data types.

For instance, a clothing retailer might possess a database that the garments have their documents with all their details, including the dimensions, brands, and color. There is also room for adding additional parameters in the future, like the size of sleeves, collars, etc.


Qualities that are what make NoSQL databases speedy:

  • They are typically explicitly designed to work with a specific pattern (i.e., key-value graph, wide column)
  • Horizontal scaling is usually done employing ranges or hashed distributions.
  • Consistency in the event: Many NoSQL stores typically have consistency later (e.g., lazy during reading time). Yet, Firestore uniquely offers solid global consistency.
  • Transactions: Many NoSQL stores do not support cross-shard transactions, nor do they have different isolation options. But, Firestore uniquely offers ACID transactions across shards that can be serialized for isolation.


Due to these characteristics, Non-relational databases are often used in applications that require colossal size, reliability, and frequent data changes.

They can increase their horizontal capacity by adding servers, as opposed to some relational databases, which can be vertically scaled by increasing the power of the machine as an increase in data—however, specific relational databases, like Cloud Spanner support scale-out and strict consistency.

Non-relational databases may house a range of non-structured data, including documents, graphs, key-values wide columns, and much more. These are the non-relational database choices within Google Cloud:

Document databases: Store data in documents (in formats like JSON or XML). For instance: Firestore

Key-value storage: Group related information in collections into records identified by unique keys to facilitate retrieval.

Key-value storage has sufficient structure to reflect the benefits of relational databases while keeping the advantages of NoSQL. For example, Bigtable, Memorystore.

In-memory database: A database designed for specific purposes that rely on memory storage for data. They are designed to achieve the shortest response time possible by removing the requirement to access disks.

They are perfect for applications that need microsecond response times and also see significant traffic increases. For instance: Memorystore.

Wide-column databases: Utilize the tabular format and permit a variety of variations in the way data is named and formatted for every row, even within one table. They are based on a standard structure , but provide a lot of flexibility. Such as Bigtable.

Graph databases: Utilize the graph structures to describe the connection distinct date stored points. They assist  in identifying patterns in semi-structured and unstructured data. Examples include JanusGraph.

Three databases are not relational within Google Cloud:

Firestore There is not any server in document database that is strongly consistent, acts as a backend-as-a-service,  offers up to 99.999% availability and scales on-demand.

DBaaS specifically created to facilitate the creation of applications. It’s perfect for general-purpose applications, including gaming, ecommerce, IoT, and real-time dashboards.

With Firestore, users can connect with and collaborate with offline and live data, making it perfect for real-time and mobile applications.

Cloud Bigtable: It is a easily filled table that may scale into thousands of columns and  billions of rows, allowing the storage of petabytes and terabytes. It is perfect for storing massive volumes of single-keyed data at extremely low latency.

It has the highest read and writes speeds at sub-milliseconds latency, and it’s a great source of data for MapReduce processes.

It is also compatible with the open-source HBase API standard that allows you to integrate to the Apache ecosystem, including Beam, HBase, the Google Cloud ecosystem, Spark and Hadoop.

Memorystore: It is a completely -controlled in-memory storage solution that works with Memcached and Redis hosted at Google Cloud. It is ideal for transient and in-memory data stores.

It automatically the complicated works of provisioning fail over,  patching and replication to allow you to work more efficiently.

Since it has extremely low latency and superior speed, Memorystore is great for mobile and web gaming, leader boards chat, social, and news feed apps. 

Conclusion


The choice of a relational or non-relational database is primarily based on the purpose. In general, if your data structure isn’t likely to change significantly, it is best to select relational data.

For Google Cloud, utilize Cloud SQL to access every all -around SQL database, and Cloud Spanner for big companies world wide scalable, robust utilize scenarios. If your data structure could be altered in the future and scale and availability are a significant need, then a non-relational database is the better option.

Google Cloud offers Cloud Bigtable , Memorystore, Firestore and to assist diverse uses across the key-value, document, and comprehensive column databases.
