AWS have recently launched Amazon EC2 Resource Optimisation Recommendations with certain similarities to 3rd party tools such as CloudCheckr, which can identify idle and underutilised EC2 instances across your accounts and regions using a combination of cloudwatch, resource usage and existing reservations can propose recommendations for reducing costs. Many individuals/companies building new instances or lifting and shifting on-premise servers often have excessive resources allocated which in the cloud world costs you money.
This guide looks at enabling EC2 Resource Optimisation to analyses your spend with the goal to ultimately reduce your AWS costs.
Global VNet to VNet peering is when you connect different virtual networks (VNet) across Azure regions. Once the connectivity is established between the virtual networks, traffic is then privately routed through the Microsoft backbone infrastructure providing a low-latency, high-bandwidth connection between your resources meaning no public internet, gateways or encryption is required in the communication between the virtual networks.
This guide shows you how to peer a VNet in the UK South region with a VNet in East US.
GuardDuty is a security monitoring service that analyses and processes VPC Flow events, CloudTrail and DNS logs. It uses threat intelligence feeds and machine learning to identify unexpected and potentially unauthorised and malicious activity within your environment such as escalation of privileges, or communication with malicious IPs, URLs, or domains. It can detect compromised EC2 instances serving malware or mining bitcoin, monitoring access behaviour for signs of compromise such as unauthorised infrastructure deployments or unusual API calls.
This article shows you how to enable GuardDuty then run a DNS query against a known bad DNS server to trigger an alert.
Amazon RDS for MySQL offers many benefits over building and maintaining your own MySQL environments giving you time to focus on application development by managing time-consuming database administration tasks including backups, software patching, monitoring, scaling and replication.
This guide shows you how to move your Joomla MySQL database from an Ubuntu server to an AWS RDS MySQL Database, although this guide focuses around Joomla it could be applied to other MySQL to RDS migrations.
AWS Session Manager is a component of AWS System Manager that allows you to manage your instances through a browser-based shell or AWS CLI. It uses a lightweight agent installed on your servers to execute server management tasks accessible through the console, this can eliminate the requirement of bastion hosts, minimise inbound ports/public ip's or maintaining SSH keys. This tool can also be extremely useful if you have lost communication to your EC2 via your normal method.
This guide shows you how to configure it to connect via SSH to a Linux EC2 and powershell to a Windows EC2 using the session manager within systems manager.
Static IP addresses are an important part of networking for many types of servers, although a bit more overhead to configure they ensure a consistent state. The Ubuntu configuration of static addresses varies depending on the operating system version you are running, this guide will look at the 2 most recent versions with Long Term Support (LTS)
This guide shows you how to configure a static IP address on an Ubuntu server running 16.04 LTS or 18.04 LTS that is currently configured with DHCP.
SSL offloading or SSL termination is removing the SSL based encryption from incoming traffic that a web server receives to eliminate the server from processing the burden of encrypting and decrypting traffic sent through SSL allowing it to focus its resources for serving web content. This also greatly reduces your SSL administration not only during the initial build and ongoing certificate renewals but also simplifies auto scaling configurations in addition to addressing certain types of security attacks away from the web servers, there is also cost savings to be had with certificate renewals and reduced server specifications without the decryption/encryption overhead.
By utilising Amazon Certificate Manager with your ALB, the certificate will be stored securely, regularly rotated and updated automatically by AWS with no action on your part and best of all it is free providing you use the AWS load balancer service. This article shows you to do the SSL offloading on an AWS Application Load Balancer (ALB).
In modern IT environments, high availability and resiliency should be ingrained into everything that is built or developed. One common area that is often overlooked is your VPN client endpoint and the issues for remote staff if there is an issue with your client vpn endpoint, if you have a hybrid on-premise/AWS cloud environment with a greater percentage of your services sitting in AWS it makes sense to move your company's VPN endpoint to a managed AWS offering, it can offer greater security, resiliancy, scalability and remove the requirement of additional licences on your VPN endpoint device.
AWS Client VPN is a managed client-based VPN service that enables you to securely access your AWS resources and resources in your on-premises network
This guide shows you how to configure a AWS Client VPN with AWS Managed Microsoft Active Directory. AWS Directory Service creates two domain controllers in separate subnets for resiliency and adding the DNS service, these run on Windows Server 2012 R2.
Understanding exactly where your business resources and data sits within the cloud is an important part of your governance, control and your geo-compliance requirements. It can also assist with reducing latency if the regions are the closest to your end users.
This guide shows you how to implement Azure region policies to only allowing your resources to be deployed in UK locations.
