AWS, JavaScript, React - Deploy Web Apps on the Cloud - Introduction to Images and Backups

The video tutorial discusses the importance of backing up cloud instances, especially as applications grow in complexity. It outlines three methods for creating disk images: manual creation through the Instance Manager, manual creation via the Lennode Backup service, and automated backups through the same service. While manual creation is cheaper, it has limitations like a 6GB size cap and a 25-image account limit. The Lennode Backup service offers a managed solution without these restrictions, allowing for scheduled backups and easy deployment of new instances. The tutorial concludes with a call to engage in hands-on exercises.

Why is it crucial to back up your instance's disks in a cloud environment?

• Because it is required by cloud service providers.

• Because it speeds up the development process.

• Because it reduces the cost of cloud services.

• Because it ensures data safety as applications grow in complexity.

Which of the following is NOT a method for creating disk images?

• Using the Instance Manager manually.

• Using the Lennode Backup service manually.

• Enabling automated backups through the Lennode Backup Service.

• Using a third-party cloud service.

What is a limitation of creating images manually through the Instance Manager?

• It can only be done once a month.

• It has a maximum image size limit of 6 gigabytes.

• It requires a separate data center.

• It is more expensive than using the backup service.

What is one advantage of the Lennode Backup service over manual image creation?

• It stores backups on the same hardware as the instance.

• It is available in select regions only.

• It requires manual intervention for each backup.

• It automatically manages image creation without size restrictions.

How does the Lennode Backup service handle the storage of backups?

• Backups are stored in a different data center.

• Backups are stored on the same hardware as the instance.

• Backups are stored in the cloud provider's main office.

• Backups are stored in the same data center but on separate dedicated hardware.
