The source from AWS HQ (private forum) was very clear and useful to pass the cloud practitioner exam. Make sure to get atleast 80% in all the separate modules which will utimately help to succeed.

@marcus-m-higgin why is DynamoDB HA by default??

DynamoDB databases are Highly available by default unlike RDS so to ensure HA you should focus on enabling Multi-AZ on the RDS PostgreSQL

Generally speaking, billing spikes come when you leave EC2 running, when EBS snapshots continues piling up, and also with NAT Gateway data transfer. S3 data transfer and CloudWatch logs can also grow without you noticing it. Background services and logs are common causes behind cost spike.

Disaster recovery is necessary for projects that under go a lot of damages, like revenue loss, or trust loss, when downtime occurs. However, for most small projects regular backups and snapshots are enough.

Auto Scaling will add real value when your traffic becomes unpredictable or downtime are frequent. However, for small projects, it is usually unnecessary. When you enable it too early, you might have to deal with complexity, extra services, and surprise costs.

I don't think basic hosting can be compared with Cloudwatch based on the features and performances. CloudWatch is advance service that offers deep, real-time metrics, logs, and customizable alarms across many services. Basic hosting tools usually show simple server stats like uptime and traffic.

I have. I think every one, especially beginners, should start with free tier to see whether it works for you or not, or whether it is appropriate service for your projects or not.

I believe it depends on how fast you can grab the technicalities related to AWS. Perhaps, along with learning how to use it, you can start using Free Tier, so that you can learn from your personal experience rather than reading knowledgebase articles or watching videos.

Hello JennyorAlice, nice to see you here, welcome to the community.

If you are just starting out with AWS, you need to estimate AWS costs first by modeling normal traffic, then adding a buffer for spikes and setting strict budgets and alerts. Fixed or tiered plans are easier for beginners because bills are predictable. AWS can be better when usage patterns are...

As far as I know Lambda and Azure, both are good for small apps. They are usually free at low traffic. Costs rise with execution time and number of requests, not server size. I believe Azure is more beginner friendly for monitoring because its cost views and alerts are simpler. AWS is powerful...

I’ve used Google Cloud Storage but not AWS S3 yet, so I might not be able to draw comparisons based on my personal experience, however, I can analyze based on what I know. I find Google Cloud Storage simple and slightly cheaper per gigabyte, with easy pricing and built-in multi-region options. I...

Multi region setups on AWS offer flexibility and global performance, however, you will end up paying more and also have to handle flexibility. but they add real cost and complexity. Traditional multi server hosting is simpler and cheaper, but it is less flexible. I think for small and medium...

An AWS Elastic IP is a public IP you can quickly move between instances if one fails. A static IP on a VPS is fixed to one server. Elastic IPs add flexibility and recovery options, while VPS static IPs are simpler but less flexible. You can certainly use for small websites if cost is not your...

One common mistake most beginners make regarding CloudWatch is assuming that it works automatically without setup. Many people forget to create alarms, check logs, or monitor key metrics, which can lead to performance drops or costs increase.

You can handle backups on AWS by automating with AWS Backup, snapshots, and versioning. You can also store copies in different regions. For disaster recovery, design for redundancy using multiple availability zones.

AWS backups are stored across multiple locations, and it is automated. Traditional hosting backups, on the other hand, are limited and manual. AWS gives better reliability and recovery options. However, beginners might find traditional hosting easier for managing small websites.

Lightsail is better than EC2 for beginners because it offers easy setup and flat pricing. EC2 is powerful than Lightsail but you need to understand networking and security groups. If you want quick results, choose Lightsail. Pick EC2 when you want full control and deeper AWS learning.
