Cloud Spanner is a scalable, serverless, and highly available relational database service designed for mission-critical applications. It offers transactional consistency at global scale, horizontal scalability, and industry-leading performance and availability.
There is no right or wrong answer to this question since it depends on the specific needs of the situation. However, Cloud Spanner is a highly scalable and reliable database service that offers strong consistency and transaction support.
Which of the following are features of Cloud Spanner?
A relational database is a database that is built for scale. It has all of the features you would expect from a relational database, including schemas, SQL queries, and ACID transactions. It is also battle-tested and ready to scale globally.
A high availability database is a database that is designed to be always available. It is automatically sharded, which means that it is divided into multiple pieces that can be spread across multiple servers. This ensures that if one server goes down, the others can continue to serve the data.
Option D is correct: Cloud Spanner is a global SQL database service that can scale across the globe horizontally and even supports ACID transactions.
What is Cloud Spanner
Cloud Spanner is a great choice for mission-critical relational database needs that require transactions at global scale with high availability. The two SQL dialects supported, GoogleSQL (ANSI 2011 with extensions) and PostgreSQL, provide a lot of flexibility.
Cloud Spanner can scale horizontally easily with minimal intervention. You can scale horizontally by just increasing the number of nodes (just change one digit). Scaling horizontally means thousands of small machines will do the work together for you.
What is the feature of Spanner?
Spanner is a distributed database system developed by Google. It is a scalable, highly available, and transactional database system that supports strong consistency.
Spanner is designed to be the foundation for a global, cloud-native application. It offers features that are not available in other relational or NoSQL databases, such as:
Transactions can be applied across rows, columns, tables, and databases within a Spanner universe
Clients can control the replication and placement of data using automatic multi-site replication and failover
Replication is synchronous and strongly consistent
Spanner is a great choice for applications that need global data consistency, high availability, and strong transactional support.
Google Cloud Spanner is a great option for those looking for a distributed relational database service that runs on Google Cloud. It is designed to support global online transaction processing deployments, SQL semantics, highly available horizontal scaling and transactional consistency.
Which of the following is the correct statement about cloud computing Mcq?
Abstraction and virtualization are two essential concepts of cloud computing. Abstraction allows for resources to be pooled and shared among users, while virtualization provides a way to create and manage virtual resources that can be used by users on demand. Together, these two concepts allow for a more efficient and effective use of resources, which is why they are essential to cloud computing.
Cloud Spanner is a managed service that provides many benefits to DBAs, including the ability to focus on application logic instead of managing hardware and software, scale out RDBMS solutions without complex sharding or clustering, and gain horizontal scaling without the need to migrate from relational to NoSQL databases.
Which of the following is the most important area of concern in cloud computing * Mcq
There is no doubt that security is the most important concern of cloud computing. With the increase in data breaches and cyber attacks, organizations are becoming more aware of the need to secure their data. However, the challenge lies in finding the right balance between security and convenience. While some organizations are willing to sacrifice convenience for security, others are more concerned with ensuring that their data is accessible and easy to use.
Cloud Spanner is a scalable, highly available, and strong consistency database service offered by Google Cloud Platform. It supports automatic scaling, synchronous data replication, and node redundancy to achieve up to 99999% availability for mission critical applications. Google’s internal Spanner service has been handling millions of queries per second from many Google services for years, making it a reliable and battle-tested solution for businesses of all sizes.
How data is stored in Spanner?
Google’s Colossus distributed replicated file system is a great way to store data. It provides huge advantages when it comes to redistributing load, as the data is not linked to individual nodes. If a node or a zone fails, the database remains available, being served by the remaining nodes.
The emulator offers the same APIs as the Spanner production service and is intended for local development and testing, not for production deployments. The emulator supports all languages of the client libraries. You can also use the emulator with the Google Cloud CLI and REST APIs.
Can Cloud Spanner automatically scale up
Autoscaler is a great tool for automatically increasing or reducing the number of nodes in Cloud Spanner, based on utilization. This can help save on costs, and make sure that resources are used efficiently.
Creating a database in Spanner is a simple process. You first need to go to the Spanner Instances page in the Google Cloud console. From there, select your instance and click on the “Create database” button.
In the next screen, you will need to provide a name for your database. You can also select a database dialect. If you are using Google Standard SQL, you can leave the Define your schema text field blank for now. Once you are done, click on the “Create” button.
How do you scale a Cloud Spanner?
If your CPU utilization is below 50% and you have capacity available, you can scale up your Spanner instance by adding more nodes.
A spanner is a type of wrench that is used to loosen, fasten, or adjust nuts and bolts. Spanners have a shaped opening that is designed to fit around a nut or bolt, or they may have jaws that are designed to grip the head of a bolt. These tools are used in a variety of settings, and they require a high-quality raw material for a long lasting life.
There is no one definitive answer to this question.
The correct answer is that Cloud Spanner is a scalable relational database service that supports transactions and SQL queries.
