Block storage is a key foundation to most file systems. File sharing and
file locking are important processes for sharing cloud data resources, and for eliminating
race conditions. Efficient implementation can make a significant mark on your system's and applications' performance levels. In this article, we use an open source example — cloud platform Eucalyptus and
its storage component Walrus — to demonstrate how to modify block storage to improve the
file-sharing and -locking mechanisms. Learn how to install Eucalyptus so you
can deliver a top-notch Infrastructure-as-a-Service platform.
