The latency test results show that the connectivity from APAC to EMEA and Americas regions has the highest latency values, ranging from 162 ms to 380 ms. This indicates that there is a significant delay in the network communication between these regions, which could affect the performance and availability of the cloud services. The connectivity from EMEA to all regions also has high latency values, ranging from 60 ms to 328 ms, which could also cause issues for the application deployment team. Therefore, these locations need to be investigated further to identify and resolve the root cause of the network latency.
Some possible causes of network latency are :
Congestion: The network bandwidth may be insufficient to handle the volume of traffic, resulting in packet loss, retransmission, and queuing delays.
Distance: The physical distance between the source and destination nodes may increase the propagation delay, which is the time it takes for a signal to travel through a medium.
Routing: The network topology and configuration may affect the number and quality of hops that a packet takes to reach its destination, resulting in transmission and processing delays.
Hardware: The performance and capacity of the network devices, such as routers, switches, firewalls, and servers, may affect the speed and efficiency of data processing and delivery.
Some possible solutions to reduce network latency are :
Scaling: The network resources can be increased or optimized to handle the traffic demand, such as adding more bandwidth, load balancers, or caching servers.
Location: The network nodes can be placed closer to each other or to the end users, such as using edge computing, content delivery networks (CDNs), or regional cloud data centers.
Routing: The network routes can be improved or optimized to reduce the number and distance of hops, such as using direct peering, dedicated circuits, or software-defined networking (SDN).
Hardware: The network devices can be upgraded or replaced with faster and more reliable ones, such as using solid-state drives (SSDs), fiber-optic cables, or 5G technology.
