This inefficient architectural design is driving increased interest in active-active configurations.</p><p class="jumpTag"><a href="/article/3216465/techology-business/how-to-know-if-an-active-active-architecture-right-for-you.html#jump">To read this article in full or to leave a comment, please click here</a></p></section></article>
