Gateway- Traditionally gateways have been used to bridge across different network providers or between on-premise and cloud or even two similar but different origin network stacks. Gateways also help with load balancing, routing, and proxy duties. Some network providers are savvy to include this technology within their offering so that they are not customized everywhere.
Cache-A cache enables requests to be handled by providing the resource without looking it up in deeper layers. The technology can span across networks or serve at many levels deep in the stack. Cache not only improves performance but it also saves costs.
Checksum – This is a simple way to check data integrity and it suffices in a place where encryption may not be easy especially when keys required to encrypt and decrypt cannot be secured. This simple technique is no match for the advantages from encryption but it is often put to use in low-level message transfers and data at rest.
Containers – Data is organized as per the units of the organization from the network device or appliance. These containers however do not necessarily remain the same size because a user dictates what is packed in any container. Therefore, when it comes to data transfer, we can transfer a large container at a time or smaller. Also, users often have to specify attributes of the container and sometimes it could go wrong. Instead of correcting a container beyond salvage, it might be easier to recreate another and transfer the data. The network favors chunked data in transit so it is up to the network and the layer above to agree where the storage unit of data will be divided up into packets with assembly at the receiving end.
Aging – Generally the older the data, the lesser the activity on the data. The data age is progressive on the timeline. Therefore, it is easier to label the data as hot warm, and cold so that the cut-off for age-related treatments may then be taken. Cost savings on the cheaper network was touted as the primary motivation earlier but this has recently been challenged. It is easier to de-duplicate when data does not change and is posed for retiring.
