what is wan accelerator and how it differentiate to sd wan

WAN is used when branch offices and headquarter based data centers are connected via MPLS. The data is transferred from sender to receiver based on TCP/IP connection mainly.

WAN Acceleration
WAN acceleration is comprised typically of optimization techniques or areas such as traffic shaping which implies that you are making the best use of the available bandwidth by assigning prioritization to the applications which are business-critical which further leads to bringing up the Quality-of-Service.

Quality of service mechanism is useful in aligning your business needs and making bandwidth consumption optimally.

The next type here is Caching, caching refers to the use of replicated data by sight and hence making it more localized, instead of it being at the faraway location where you are pulling from the server. Here, you are actually making it appear that you are pulling the information locally and thus leading to optimization of time required for accessing the information. For example, if we are continuously clicking on the same link again and again, the information is cached and kept in place and therefore it seems it's faster response time unless a new update comes through and it will have a contact to the server.

Compression, Protocol optimization, and File services which also make use of the caching technique can be further used for WAN optimization.

Why SD-WAN?
SD-WAN comes with cloud-first technology. Traffic patterns are changing since users are shifting to more reliable methods of transmission, that is applications are cloud-based, as in AWS (Amazon Web Services), Microsoft Azure, Office365, DropBox, or SAAS (Software as a Service) apps, etc.

SD Wan means Software-Defined Wide Area Network. In this model, the apps hosted on the internet are further accessed by the use of the internet. Which means, traffic is not routed by looking at the addresses in the network routing table (as in WAN) but SD-Wan utilizes software for the effective routing of the traffic across the WAN as per the business requirements. SD-WAN ensures application performance is further improved and as well as improved security across the WAN.
