So we use Packer and Vagrant to unify the production environment and development environment, Packer build operating system images for Vagrant to run the virtual development environment, so that all developers have a unified and continuously updated development environment, more conducive to reduce problems and collaboration.
Packer-built mirrors are also available for large virtualization platforms such as KVM, Xen and ESXi, as well as

We can also tell HOST1 to connect HOST2, or both tell them that there is no problem, weave will automatically connect, after their service startup, we can also tell weave to connect multiple peers, you can provide multiple IP addresses, separated by a space.

The code is as follows:

As one of the core services of cloud computing, storage services are used by every user. However, the current situation is: most customers in addition to virtual machine data disk (persistent disk), and does not fully utilize the storage services. Let's look at a typical scenario: for example, a Web application needs a user to upload an invoice scan (image file). At the code implementation level, the image files uploaded by the user are usually saved directly to the disk file system. In a tradit

What is the status of the OAuth framework during API creation? Is this method still feasible?

Transform: The return value of the transform is a new Rdd collection, not a single value. Call a transform method, there will be no evaluation, it only gets an RDD as a parameter, and then returns a new Rdd.Transform functions include: Map,filter,flatmap,groupbykey,reducebykey,aggregatebykey,pipe and coalesce.Action: The action operation calculates and returns a new value.

For real-time streaming of Big data, AWS offers both legacy and full host scenarios
The legacy scenario is EC2 Deployment Flume (Capture), Kafka (data Dump), Storam (Stream processing)
The full host scenario is kinesis
The use of Kinesis still requires the user through
