The best thing about opsters is their great customer service team who are always eager in helping us find any solution for our problems or queries we have with them whenever required! Their support staff has been very responsive & patient during my tenure as an employee at OPM Solutions Limited (OPM).
I would highly recommend using this firm if ever looking out solutions related elastic search operations like searching data from multiple sources into one place so it becomes easy when querying all those fields together without having separate indexing again!! We were able solve many issues regarding ES cluster configuration / performance tuning etc., which gave me peace mind knowing there was someone available 24/7 should i require help anytime around midnight PST time zone!! Also they helped migrate existing production environment setup by doing some extra configurations before migrating over new clusters within same server room but still achieving desired results unlike other firms where migration process took 3 days due lack expertise! Highly recommended anyone.
