Where AWS Route53 manipulates DNS responses, AWS Global Accelerator utilizes IP anycast to improve the availability and performance of applications. AWS Global Accelerator uses static anycast IP addresses to route user traffic to the optimal AWS endpoint based on proximity, health, and routing policies: Figure 6.22 – AWS Global Accelerator using one IP for three […]
In addition to traffic distribution, Amazon Route53 health checks can be configured for each record to ensure traffic is only sent to healthy nodes. The next figure shows the health check configurations for our pair of WireGuard VPN servers in an AWS Local Zone: Figure 6.17 – Amazon Route53 health checks for two WireGuard VPN […]
The first step in the process is to navigate to the AWS Direct Connect page within the AWS Management Console and click Create Connection. Under Connection ordering type, select Classic. Next, choose the appropriate Location from the drop-down menu. Port speed options will vary depending upon the location chosen—only a subset will offer 100 gigabits […]
Migrating to the cloud and updating your infrastructure can be tricky. The simultaneous migration of interconnected applications can be challenging; thus, many choose not to entirely abandon their infrastructures in one shot. An incremental approach to lift-and-shift migrations was typical even before AWS Local Zones were introduced. Figure 6.5 – Migrating from VMware to EC2 […]
While there are many use cases for AWS Local Zones, the drivers behind all of them boil down to three things. Reduced latency In today’s digital landscape, many tasks, including medical image processing, real-time gaming, telco virtualization, and enterprise transactions, necessitate fast access to compute power with minimal lag. Figure 6.2 – Customers in Texas […]
In the world of cloud computing, latency is the invisible force that can determine the success or failure of an application. From augmented reality experiences requiring instantaneous feedback to mission-critical industrial applications where every millisecond counts, reducing latency is pivotal. As we journeyed through AWS’s vast edge computing landscape, it became evident that proximity to […]
Amazon EBS volumes are not supported on Outposts servers; only instance store volumes are available. Similar to the in-region instance store, the instance store data persists after a reboot but not an instance termination. This means customers must use either stateless configurations or must back up instance data to a persistent destination such as Amazon […]
AWS Outposts servers offer HA through the use of redundant power equipment that can be paired with dual customer-provided power sources for even greater resilience. Power is critical to any compute resource but network connectivity is also critical for Outposts deployments as management, monitoring, and service operations need connectivity to the anchor AZ. However, Outposts […]
Statistically, it is quite rare for hardware failure to be the source of an outage that impacts application availability. Most are caused by misunderstandings of logical dependencies during maintenance. A good way to prevent this impact is to have a completely separate Outposts Rack deployment that is tied to a different parent region. These twin […]
RDS is a managed service that makes it simple to set up, operate, and scale databases in the cloud. The following database engines are available within an AWS Outposts Rack deployment: RDS for SQL Server RDS for PostgreSQL RDS for MySQL These databases have the advantage of being close to on-premises applications that require low […]
