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 […]
This method of load balancing expects new connections to issue a fresh DNS query each time. Thus, it is prudent to consider the caching behavior of the client devices, as well as any DNS servers between them and Amazon Route53. By default, the Time To Live (TTL) of an A record in Amazon Route53 is […]
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 […]
For use cases where resources in an AWS Local Zone need to communicate with resources in an on-premises data center in that same metro area, there are two basic approaches. The first is a physical connection via AWS Direct Connect and the second is a virtual connection via a VPN over the public internet. Both […]
Tools such as the AWS latency tester [https://aws-latency-test.com] help predict the latency benefits that a given device will experience when connecting through an AWS Local Zone vs a region: Figure 6.6 – AWS Local Zone latency test output This figure shows a small snippet of the output of this tool. It will geolocate the client’s […]
Outposts’ capacity is finite. As it is a physical installation, any expansion requires careful planning and potentially additional hardware. Customers need to monitor usage and predict future needs. The elasticity inherent to the cloud is present in Local Zones. While there might be soft limits, scaling resources is more straightforward, not requiring hardware interventions. Security […]
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 […]
