Cloud Interview Questions and Answers
Ques. 1): How effective are Lightsail instances?
Answer:
AWS particularly designed Lightsail instances for usage with web servers, developer environments, and tiny databases. Such tasks occasionally require a performance burst but do not frequently or routinely demand the entire CPU. Burstable performance instances, which Lightsail employs, offer a basic amount of CPU performance with the option to burst over it. This approach protects you from the inconsistent performance or other frequent negative effects that you may normally see from over-subscription in other situations while enabling you to obtain the performance you need, when you need it.
Use Amazon EC2 if you want highly customizable settings and instances with consistently good CPU performance for applications like video transcoding or HPC workloads.

Ques. 2): How do DNS records work?
Answer:
DNS is a widely used service that converts domain names like www.example.com into the numerical IP addresses used by computers to communicate to one another, such as 192.0.2.1. You may quickly link the public IPs of your Lightsail instances to your registered domain names, such as photos.example.com. In this way, Lightsail automatically converts human readable names like example.com that people put into their browsers into the IP of the instance you wish to send them to. These translations are all referred to as DNS queries.
It's crucial to understand that you must register a domain in Lightsail before using it. You can register new domains using Amazon Route 53, or your preferred DNS registrar.

Ques. 3): What can I do in Lightsail using tags?
Answer:
With tags, you can categorise and filter your resources in the Lightsail interface and API, keep track of and arrange your charges in your bill, and set access management rules to control who may see or alter your resources. With the use of tags, you can:
Organize - View and manage resources based on the tags you've given them using the Lightsail interface and API filters. This is helpful if you have a lot of resources of the same type since you can easily recognise a particular resource based on the tags you've given it.
Cost-allocate - By identifying your resources and setting "cost allocation tags" in the billing interface, you may track and distribute expenses across various projects or users. You may, for instance, break out your bill and analyse your expenditures by client or project.
Using AWS Identity and Access Management rules, you can manage access and limit who may create, update, and remove Lightsail resources. You can work more effectively with people on projects without having to grant them complete access to your Lightsail resources thanks to this.

Ques. 5): What are photographs?
Answer:
Point-in-time backups of instances, databases, or block storage devices are known as snapshots. You may take a snapshot of your resources at any moment, or you can instruct Lightsail to take snapshots for you by turning on automatic snapshots for instances and discs. Snapshots can be used as starting points for building new resources or when backing up data. All the information required to recover your resource is in a snapshot (from the moment when the snapshot was taken). The rebuilt resource starts out as an identical clone of the old resource that was used to construct the snapshot when you restore a resource by building it from a snapshot.
You can manually take snapshots of your Lightsail instances, disks, and databases, or you can use automatic snapshots to instruct Lightsail to take daily snapshots of your instances and disks automatically.

Ques. 8): What are the maintained databases at Lightsail?
Answer:
The managed databases offered by Lightsail are instances that are solely used to operate databases rather than other workloads like web servers, mail servers, etc. The same tools and programmes you use to access a stand-alone database may also be used to access a Lightsail database, which can contain many user-created databases. Lightsail keeps your database's operating system and underlying infrastructure safe and secure so that you may administer a database without having a strong background in infrastructure management. Lightsail databases have a defined amount of memory, processing power, and SSD-based storage that you can scale up over time, much like standard Lightsail instances. Your selected database will be installed and configured for you by Lightsail immediately after it is created.

Ques. 9): What can I do with the block storage in Lightsail?
Answer:
Similar to an individual hard drive, Lightsail block storage offers extra storage volumes (referred to as "connected discs" in Lightsail) that you may attach to your Lightsail instance. Applications and software that need to split off specialised data from their core services can benefit from attached discs. They can also be used to preserve application data in the event that your instance and system disc experience a failure or other problem. Applications or software that often access their stored data might benefit from the constant performance and reduced latency provided by attached drives.
Solid-state discs are used in Lightsail block storage (SSD). This kind of block storage aims to handle the great majority of Lightsail workloads by balancing affordability and performance. Adopt EC2 with GP2 or Provisioned IOPS SSD storage in place of Lightsail for clients whose applications need consistent IOPS performance, high throughput per disc, or are running sizable databases like MongoDB, Cassandra, etc.

Ques. 10): What distinguishes halting from deleting my instance?
Answer:
Your instance is shut down when you stop it, but it is still switched on and ready for you to restart it whenever you choose. It is advised to use static IPs for instances that must maintain the same IP after they cease since stopping your instance would relinquish its public IP.
Your instance will be deleted, which is a detrimental operation. Your instance data will all be lost and unrecoverable unless you have taken an instance snapshot. Both the instance's public and private IP addresses will be made public. If you were utilising a static IP with that instance, it stays in your account but is detachable.

Ques. 19): What kind of usage does Lightsail CDN encourage?
Answer:
Amazon To make the cost of utilising the service straightforward and predictable, Lightsail CDN distributions are built using fixed-priced bundles of data transport. A month's worth of consumption is covered by a distribution package. Distribution bundles may not be used for purposes other than those for which they were designed, such as repeatedly upgrading or downgrading bundles or employing an abnormally high volume of distributions from a single origin. Workloads that need a lot of requests per second or a lot of streaming video are also not allowed. Your data services or account may be throttled or suspended if you engage in these actions.

Ques. 20): What's the difference between removing my container service and halting it?
Answer:
Your container nodes are in a disabled state when you disable your container service, and the public endpoint of the service returns an HTTP status code of '503'. The service returns to the most recent active deployment when it is enabled. Configurations for power and scalability are also kept. Following re-enabling, the public endpoint's name remains unchanged. Container images and deployment history are kept.
You are acting destructively when you remove your container service. All of the service's container nodes will be permanently destroyed. Additionally, your service's container images, deployment history, logs, and HTTPS public endpoint address will all be permanently erased. It is impossible for you to get the endpoint address back.
