title: CAP theorem - Availability and Partition Tolerance
body: <p>While I try to understand the "Availability" (A) and "Partition tolerance" (P) in CAP, I found it difficult to understand the explanations from various articles. </p>
  
  <p>I get a feeling that A and P can go together (I know this is not the case, and that's why I fail to understand!).</p>
  
  <p>Explaining in simple terms, what are A and P and the difference between them? </p>
