Select your instance plan based on your needs. For a small blog or a personal website, the lower-cost plans are often sufficient. For this demo, I will choose 5 USD, and scroll down.

Step 3: Configure Your Instance

Name your instance—this could be something relevant to your site or simply “Demo-instance.”

Optionally add tags to organize your resources if needed. Click Create Instance. LightSail will begin the process of deploying your WordPress site on the instance.

Step 4: Accessing Your WordPress Site

Once the instance is up and running (it usually takes a few minutes), you can access your WordPress site:

Go to the LightSail instances page and access the newly created instance.

Under the Connect tab, you’ll find the Public IP of your instance. This is the IP address you’ll use to access your WordPress site. Enter the IP in a browser, and you’ll see your new WordPress site live.

Step 5: Logging Into Your WordPress Admin Panel

To access the WordPress admin dashboard:

Add /wp-admin to the IP address in your browser. Example: http://<your-instance-ip>/wp-admin.

The default credentials (username and password) for your WordPress admin dashboard can be retrieved from the instance management page:

Under the Connect tab, click on SSH to open a terminal window.

Run the following command to retrieve the password:

cat bitnami_application_password

Guide to AWS Public, Private, and Elastic IPs: Understanding AWS IP Addressing

IP addresses enable communication between resources, instances, and users. Whether you’re building a cloud-based application, managing an EC2 instance, or configuring network infrastructure, it’s essential to understand the types of IP addresses AWS offers: Public, Private, and Elastic Ips.

This blog explores these three types of IPs, their use cases, and best practices for managing them in your AWS environment.

What is a Public IP in AWS?

A Public IP is an address that allows AWS resources to communicate directly with the internet. When you launch an EC2 instance, for example, it can automatically receive a public IP address, enabling it to be accessed over the public Internet.

Key Features:

They are dynamic, meaning they can change whenever an instance is stopped and restarted.
They are automatically assigned unless you specify otherwise.
They allow inbound traffic from the internet and outbound internet communication.

Use Cases:

Web servers: If you’re hosting a website or application that users access over the internet, a public IP is essential.

Publicly accessible APIs: APIs that external users or systems need to access will require public IPs.

Best Practices:

Limit the exposure of public IP addresses to minimize security risks.

Use AWS security groups and Network Access Control Lists (NACLs) to restrict unwanted traffic.

What is a Private IP in AWS?

A Private IP is used for communication between AWS resources within the (VPC). Private IPs allow resources to communicate securely within a closed network without exposing them to the public internet.

NAT Devices and Gateways.

Machines in a private network connect to the internet through NAT devices and internet gateways acting as proxies.

Key Features:

Private IP addresses are unique within a VPC.
Resources with private IPs can only communicate within the VPC or through a VPN/Direct Connect for private networks.
Unlike public IPs, private IP addresses do not change when an instance is stopped and started.

Use Cases

Internal application communication: For services like databases, back-end servers, and other internal resources, private IPs ensure that only internal AWS resources can connect to them.

Secure networking: Resources with private IPs can communicate securely without being exposed to external networks.

Public vs. Private IP: When to Use Each

The key difference between public and private IPs in AWS is their scope and exposure to the internet. Public IPs allow internet traffic, while private IPs restrict communication within the VPC.

What is an Elastic IP in AWS?

An Elastic IP (EIP) is a static public IP address designed to provide a permanent address for your resources in AWS. Unlike public IPs, which are dynamically assigned and can change, Elastic IPs remain constant even when the instance they are attached to is stopped or rebooted.

Key Features:

Elastic IPs allow you to keep the same IP address even if you stop and start your instance.
They are particularly useful for services or instances that require a static IP for DNS or continuous communication.
Elastic IPs are charged if they remain allocated but are not associated with any running resource.

Use Cases

Reassignable IP for failover: Elastic IPs are often used for failover scenarios where the IP needs to be transferred between instances.

Static IP for applications: Services that need a fixed IP address, such as a public-facing service with DNS records.

Demo: How to Allocate and Associate an Elastic IP to an EC2 Instance

Make sure you have one EC2 instance running then navigate to the EC2 Dashboard by selecting EC2 from the services menu.

On the left-hand sidebar, scroll down and click Elastic IPs under the “Network & Security” section.

Click the Allocate Elastic IP address at the top of the page.

Leave the settings as default and click on the Allocate IP button.

Associating Elastic IP: Click on the allocated elastic IP address then click on associate Elastic IP address.

Under resource select Instance, then under Instance select the Instance you want to associate with the Elastic IP address.

You can check the box on reassociate to allow the elastic IP to be reassociated with a different resource if it’s already associated. Then click on the associate button.

Successfully associated, make sure to clean up by disassociating and realising the IP address.

Best Practices:

Only use Elastic IPs, when necessary, as AWS charges for unused EIPs.

Implement monitoring and failover strategies to reassign Elastic IPs when an instance fails.

Consider using an Elastic Load Balancer (ELB) for services requiring high availability rather than using Elastic IPs.

Conclusion

AWS Public, Private, and Elastic IPs each serve specific purposes in cloud networking. Public IPs facilitate internet-facing communication, private IPs provide secure internal networking, and Elastic IPs provide a static, unchanging IP address that can be reassigned to different instances as needed.

Thanks for reading and stay tuned for more. Make sure you clean up.

Grafana dashboard with AWS CloudWatch metrics

A Comprehensive Guide to Dynamic Grafana Dashboards Using AWS CloudWatch

Introduction

In today’s fast-paced cloud environments, real-time monitoring and visualization are key to ensuring your infrastructure operates efficiently. Grafana dashboards, when combined with AWS CloudWatch, offer a powerful solution for visualizing and analyzing data from your AWS services. In this blog, we will walk you through setting up Dynamic Grafana Dashboards using AWS CloudWatch metrics.

What is Grafana?

Grafana is an open-source platform designed for monitoring and observability. It allows users to query, visualize, alert, and explore metrics no matter where they are stored.

Why Use Grafana with AWS CloudWatch?

AWS CloudWatch is Amazon’s monitoring and observability service. While CloudWatch offers built-in visualization options, they can be limited in flexibility and customization. This is where Grafana dashboards come in.

With Grafana, you can:

Create dynamic, interactive dashboards
Visualize multiple data sources, including CloudWatch metrics
Share and export dashboard views
Build real-time monitoring dashboards that are highly customizable

Let’s get into the hands-on

We will first start by launching an EC2 instance.

To launch an EC2 instance for running Grafana, you can follow these steps:

Log in to the AWS Management Console

In the search bar type EC2 then select EC2 under services.

In the EC2 Dashboard, choose Instances from the navigation panel on the left side.

Click on the Launch Instances button.

Enter your preferred name for the instance in the name field.

Under Application and OS Images, select the Quick Start tab, then choose your preferred AMI. For this setup, I will select Ubuntu.

Under Instance Type, you can select t2. Micro, which is free tier eligible. However, for this project, I will choose t2. Medium.

Next, under Key Pair (login), select your existing key pair.

Under Firewall, select the Create New Security Group radio button. Then, open the following ports

Port 22 for SSH
Port 80 for HTTP
Port 443 for HTTPS

Always follow best practices when configuring SSH ports by limiting access to your IP address.

Leave storage as the default, then review it and click launch instance.

After launching the instance, adjust its security groups by opening port 3000 for Grafana.

Click on the Instance ID, then scroll down to the Security section. Next, click on the Security Group associated with the instance.

Go to the Inbound Rules tab and click on Edit Inbound Rules.

In the Edit Inbound Rules dashboard, click on Add Rule.

In the Port Range section, enter 3000, then click on Save Changes.

Now is the time to install Grafana, SSH into your instance by entering this command in your terminal.

# ssh -i <key.pem> user@publicIP

# your code should look like this.

ssh -i web-SSHkeys.pem ubuntu@44.212.29.235

Run the system update then paste in this command to install Grafana.

wget https://dl.grafana.com/enterprise/release/grafana-enterprise-11.1.0.linux-amd64.tar.gz tar -xvzf grafana-enterprise-11.1.0.linux-amd64.tar.gz cd grafana-v11.1.0/bin ./grafana-server &

Access Grafana: Open your web browser and navigate to http://<your-server-ip>:3000. Login using the default credentials (admin/admin).

Update your new password then you will be logged in to your Grafana dashboard.

Adding CloudWatch as a Data Source

Grafana can integrate with AWS CloudWatch to visualize metrics from your AWS services.

Add Data Source: In Grafana, go to the Left panel > Connections > Data Sources and click Add data source. Select CloudWatch from the list.

Configure CloudWatch: Enter your AWS credentials, specify the default region, and save the data source.

Creating a Dashboard for EC2 Metrics

Create Dashboard: Click on the Dashboards icon in the sidebar and select New.

Add Panels: Click Add visualization, select CloudWatch-metrics as the data source, and configure queries to fetch metrics for your EC2 instances, such as CPU utilization and network traffic.

Here we have configured the first query to fetch CPU utilization of our EC2 instance running in our default region from CloudWatch.

Similarly, we will add additional queries to fetch other metrics for this instance from CloudWatch, such as Network In/Out or Status Checks.

Now save the dashboard by clicking on the save option in the right corner.

And that’s it! We have successfully achieved our objective by building a dynamic Grafana dashboard using AWS CloudWatch metrics.

Conclusion

Using Grafana dashboards with AWS CloudWatch provides real-time monitoring and valuable insights into your AWS infrastructure, helping optimize performance and manage costs effectively.
