Why not build it all yourself?
Short Answer : Its cumbersome!
You would rather spend your time and energy on analyzing the data, while the experts
do the heavy lifting for you.
But if you insist on doing it all yourself, here is the long answer. Building such a system
would require:
– A system to collect logs from disparate sources
– A system to process the data in a distributed manner
– A scalable datastore
– A distributed data indexing and caching system
– A data visualization toolkit
Additionally, you would need to take care of following aspects:
– High Availability
– Scalability
– Sizing
– Performance Tuning
