Looking for AWS Server Infrastructure Expert

Hi , We want to setup high performance wordpress clusters server over Amazon AWS for price comparision sites as per template [login to view URL] Additionally we want to replicate( synchronize) database table for wordpress woocommerce products over private IP ( networking ) in between clusters We have use case in which one server is responsible for fetching product data from various merchants If we have a single standalone server it will take years to fetch and add 400 million woocommerce products But if we attach n- number of clusters who also does the task of fetching product then this will be easy We want a architecture in which output of clusters are replicated to master server databse and is visible to users clusers can be configured on subdomain of main domain . Architecture should be self scalable and should use all the technologies as per refrence link mentioned above . We are looking for experts who can also share us SWI / Steps so that we can also setup the infrastructure on our own . We also want that freelancer should do the entire setup over shared screen like teamviewer / or can also record a video and share it with us . Payments Terms : 100% as per freeancer policy . We will not release any milestone in advance but we will deposit milestone on project acceptance Note : Replication of woocommerce product table should happen in one direction only like say we have one master DB and one failover replica DB and we have 10 small small clusters who are doing cron job and fethcing woocommerce products then product of clusters should be replicated to master DB and failover replica DB the cluster should not copy data from master DB or failover replica DB also after the product is replicated to master DB and failover replica DB the products should be deleted from cluster entire infrastructure should be based on NGINX server +Redis – the fastest object and variant cache available+ Nginx FastCGI Cache – the fastest HTTP accelerator available and it’s easy to use Thanks Sneha
