Google Meet tackles Zoom by going completely free for all Meet is one of several video chat apps Google offers : The company's Duo and Hangouts are free, but come with a fair number of limitations. Hangouts only supports up to 25 participants Duo only supports up to 12 participants.  Google also recently added several new features to Meet, including a Zoom-like grid view with support for 16 participants at once, as well as a low-light mode and a noise cancellation feature. Meet was formerly only available as a part of Google's G Suite business-oriented service package, which starts at $6 per month per person, but now it will be free to anyone with a Google account.

UDPTunnel's primary  purpose  (and  original  motivation)  is  to  allow  multi-media        conferences to traverse a firewall which allows only outgoing TCP connections. USAGE        UDPTunnel  can  be  run  in  two  modes:  a client mode and a server mode. The client mode        initiates the TCP connection before  relaying  UDP;  the  server  waits  for  an  incoming        connection  before  doing so. After the TCP connection is established, the behavior of the        two modes is identical. If you are using UDPTunnel to traverse  a  firewall  as  discussed        above,  the  client  would be run inside the firewall, and the server would be run outside        it.

WireGuard® aims to be faster, simpler, leaner, and more useful than IPsec, while avoiding the massive headache. It intends to be considerably more performant than OpenVPN. WireGuard is designed as a general purpose VPN for running on embedded interfaces and super computers alike, fit for many different circumstances. Initially released for the Linux kernel, it is now cross-platform (Windows, macOS, BSD, iOS, Android) and widely deployable. It is currently under heavy development, but already it might be regarded as the most secure, easiest to use, and simplest VPN solution in the industry.

We'll take you through the steps needed to set up docker snap work for you on ubuntu core and ubuntu classic. On Ubuntu classic, before installing the docker snap, please run the following command to add the login user into docker group.     sudo addgroup --system docker     sudo adduser $USER docker     newgrp docker On Ubuntu Core 16, after installing the docker snap from store, you need to connect the home interface as it's not auto-connected by default.     sudo snap connect docker:home :home Then have fun with docker in snappy. ubuntu@ip-172-31-8-122:~$  sudo docker run hello-world Unable to find image 'hello-world:latest' locally

 With the cloud, the collection and aggregation of account and network activities is simplified, but it can be time consuming for security teams to continuously analyze event log data for potential threats. With GuardDuty, you now have an intelligent and cost-effective option for continuous threat detection in the AWS Cloud. 

Customers may want to run a hybrid architecture of both on-premises and in the cloud.  Almost every AWS customer with on-premises infrastructure is running a hybrid architecture. AWS customers are able to use a seamless experience between their existing on-premises investments while obtaining the benefits of the AWS Cloud. AWS doesn’t require additional on-premises investments by customers to run a hybrid architecture.

Jenkins X Pipelines are built on Tekton Pipelines, which aid in running CI/CD pipelines on Kubernetes. You can configure your pipeline using a jenkins-x.yml file (compared to a traditional Jenkinsfile). Jenkins X also provides build packs, which can help package source code into images that can then be deployed to Kubernetes.

Azure Pipelines provide the platform’s CI/CD service.  Azure DevOps allows you to control nearly every stage in the DevOps lifecycle while offering many advanced container-specific features, including private container registries and integration with Azure Kubernetes Service (AKS).

The AllowTcpForwarding option in the OpenSSH server configuration file must be enabled on the server to allow port forwarding. By default, forwarding is allowed. Possible values for this option are yes or all to allow all TCP forwarding,  no to prevent all TCP forwarding,  local to allow local forwardings, and  remote to allow remote forwardings. Another option of interest is AllowStreamLocalForwarding, which can be used to forward Unix domain sockets. It allows the same values as AllowTcpForwarding. The default is yes. For example:     AllowTcpForwarding remote     AllowStreamLocalForwarding no The GatewayPorts configuration option also affects remote port forwardings. Possible values were no (only local connections from server host allowed; default),  yes (anyone on the Internet can connect to remote forwarded ports),  clientspecified (client can specify an IP address that can connect, anyone can if not specified).

To fix this error, you need to add the IdentitiesOnly with a value of yes, which instructs ssh to only use the authentication identity files specified on the command line or the configured in the ssh_config file(s), even if ssh-agent offers additional identities.

MySQL LOW_PRIORITY only affects storage engines which use table-level locking, like MyISAM and MEMORY. None of those engines support foreign key constraints.

Amazon EFS provides shared access to data using a traditional file sharing permissions model and hierarchical directory structure via the NFSv4 protocol. Applications that access data using a standard file system interface provided through the operating system can use Amazon EFS to take advantage of the scalability and reliability of file storage in the cloud without writing any new code or adjusting applications. Amazon S3 is an object storage platform that uses a simple API for storing and accessing data. Applications that do not require a file system structure and are designed to work with object storage can use Amazon S3 as a massively scalable, durable, low-cost object storage solution.

Google Fi piggybacks on existing wireless networks to deliver service. The uniqueness of  Fi is that it switches between three wireless networks -- T-Mobile, Sprint and US Cellular -- instead of using just one. The idea is that it'll switch to the best-performing network wherever you happen to be.

Amazon DocumentDB implements the Apache 2.0 open source MongoDB 3.6 API by emulating the responses that a MongoDB client expects from a MongoDB server, allowing you to use your existing MongoDB drivers and tools with Amazon DocumentDB. Updating your application is as easy as changing the database endpoint to a new Amazon DocumentDB cluster.
