It'
1s not that there is a\n lack of information out there. You can find academic papers,\n engineering blogs, and even books on the subject. The problem is\n that the available information is spread out all over the place,\n and if you were to put it on a spectrum from theory to practice,\n you would find a lot of material at the two ends but not much in\n the middle.</p> \n\n <p><strong>That is why I decided to write a book that brings together\n the core theoretical and practical concepts of distributed\n systems</strong>\n so that you don't have to spend hours connecting the dots. This book\n will guide you through the fundamentals of large-scale distributed\n systems, with just enough details and external references to dive\n deeper. This is the guide I wished existed when I first started out,\n based on my experience building large distributed systems that scale\n to millions of requests per second and billions of devices.</p> \n\n <p><strong>If you are a developer working on the backend of web or\n mobile applications (or would like to be!), this book is for\n you.</strong>\n When building distributed applications, you need to be familiar with\n the network stack, data consistency models, scalability and reliability\n patterns, observability best practices, and much more. Although you\n can build applications without knowing much of that, you will end\n up spending hours debugging and re-architecting them, learning hard\n lessons that you could have acquired in a much faster and less painful\n way.</p> \n <p>However, if you have several years of experience designing and\n building highly available and fault-tolerant applications that\n scale to millions of users, this book might not be for you. As\n an expert, you are likely looking for depth rather than breadth,\n and this book focuses more on the latter since it would be\n impossible to cover the field otherwise.</p></div></div>',f(s,"class","relative pb-16 bg-white overflow-hidden")},m(e,t){d(e,s,t)},p:e,i:e,o:e,d(e){e&&h(s)}}}class R extends _{constructor(e){super(),W(this,e,null,U,i,{})}}function G(e){let t,s,n,a,i,r,w,y,x,b,$,k,z,q,C,T,I,M,S;const A=e[4].default,j=o(A,e,e[3],null);return{c(){t=p("blockquote"),s=p("div"),j&&j.c(),n=m(),a=p("footer"),i=p("div"),r=p("div"),w=p("img"),x=m(),b=p("div"),$=p("div"),k=g(e[0]),z=m(),q=u("svg"),C=u("path"),T=m(),I=p("div"),M=g(e[1]),f(s,"class","max-w-3xl mx-auto text-center text-xl leading-9 font-medium text-gray-900"),f(w,"class","mx-auto h-10 w-10 rounded-full"),w.src!==(y=e[2])&&f(w,"src",y),f(w,"alt",""),f(r,"class","md:flex-shrink-0"),f($,"class","text-base font-medium text-gray-900"),f(C,"d","M11 0h3L9 20H6l5-20z"),f(q,"class","hidden md:block mx-1 h-5 w-5 text-indigo-600"),f(q,"fill","currentColor"),f(q,"viewBox","0 0 20 20"),f(I,"class","text-base font-medium text-gray-500"),f(b,"class","mt-3 text-center md:mt-0 md:ml-4 md:flex md:items-center"),f(i,"class","md:flex md:items-center md:justify-center"),f(a,"class","mt-8"),f(t,"class","mt-10")},m(e,o){d(e,t,o),c(t,s),j&&j.m(s,null),c(t,n),c(t,a),c(a,i),c(i,r),c(r,w),c(i,x),c(i,b),c(b,$),c($,k),c(b,z),c(b,q),c(q,C),c(b,T),c(b,I),c(I,M),S=!0},p(e,[t]){j&&j.p&&8&t&&l(j,A,e,e[3],t,null,null),(!S||4&t&&w.src!==(y=e[2]))&&f(w,"src",y),(!S||1&t)&&v(k,e[0]),(!S||2&t)&&v(M,e[1])},i(e){S||(P(j,e),S=!0)},o(e){L(j,e),S=!1},d(e){e&&h(t),j&&j.d(e)}}}function F(e,t,s){let{$$slots:n={},$$scope:a}=t,{name:i}=t,{role:o}=t,{imagePath:r}=t;return e.$$set=e=>{"name"in e&&s(0,i=e.name),"role"in e&&s(1,o=e.role),"imagePath"in e&&s(2,r=e.imagePath),"$$scope"in e&&s(3,a=e.$$scope)},[i,o,r,a,n]}class O extends _{constructor(e){super(),W(this,e,F,G,i,{name:0,role:1,imagePath:2})}}function V(e){let t;return{c(){t=p("div"),t.innerHTML='<iframe width="560" height="315" src="https://www.youtube.com/embed/83o-LNw3Eps" title="YouTube video player" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture" allowfullscreen=""></iframe>',f(t,"class","flex flex-col justify-center items-center")},m(e,s){d(e,t,s)},d(e){e&&h(t)}}}function K(e){let t;return{c(){t=p("p"),t.textContent="âUnderstanding Distributed Systems fills the void\n between the deep theory and the \"interview preparation\"\n focused books.

1 discusses the benefits of\n offloading the storage of large static files, such as images and videos,\n to a managed file store.
