Azure and AWS for multicloud solutions

As the leading public cloud platforms, Microsoft Azure and Amazon Web Services (AWS) each offer businesses a broad and deep set of capabilities with global coverage.

Yet many organizations choose to use both platforms together for greater choice and flexibility, as well as to spread their risk and dependencies with a multicloud approach. Consulting companies and software vendors might also build on and use both Azure and AWS, as these platforms represent most of the cloud market demand.

Microsoft’s cloud computing platform Microsoft Azure includes a CDN service in their offering.

The Azure CDN service uses the networks of Akamai and Edgecast, though it is fully integrated with the cloud platform and offered under the Azure brand.  Because the CDN service is offered as a part of the larger Azure IaaS ecosystem, it is easy-to-use for businesses who already use the platform. Other CDNs can be used in combination with Azure products as well, for example with their storage solution.

Azure is an Infrastructure-as-a-Service (IaaS) solution, and next to a CDN they offer storage solutions, data management, compute and networking. Their IaaS solution is similar to Amazon Web Services (AWS) and Google Compute Engine (GCE). Just like Google, Azure offers free credit to first-time users of the platform to help them get started.

Cloudfront is a CDN by Amazon, which can be used on a stand-alone basis, or in combination with other Amazon web products.

Cloudfront CDN integrates very well with Amazon Web Services (AWS), and is often used in combination with their storage solution Amazon S3.
Amazon Cloudfront offers on-demand, no-commitment pricing plans which can be found on their website. The pricing overview of Cloudfront is slightly complex; customers should be aware that the unit prices for bandwidth and requests differ per region.

How to import key or database file into miniKeepass or KeePass Touch

Then choose Export

 Then choose 'Open in...'
 You see  miniKeepass or KeePass Touch ( You won't see them if you didn't choose 'Open in ...')

KGif is a teeny-tiny tool that creates an animated gif from the active window on your Linux desktop.

To get started download or save the script from GitHub. Place it in your Home folder (or a scripts folder, and then cd into its location). To use KGif run it from the Terminal using: ./kgif.sh Naturally you might not be ready to start recording. You can use a delay value to specify how long (in seconds) the script should wait before it starts capturing. E.g.: delay=7 ./kgif.sh The output is saved in the same folder, where it is named ‘terminal.gif‘, and all the accrued .png images are deleted automatically.

If GIF is so bad why use it at all?

While GIF is a very old format, it has seen some rise in usage again in recent years. One reason is its easy usage in the Web. GIF files are supported nearly everywhere, which means you can add animations easily to everywhere where you can upload images. With real video files you are still more limited.

How to exclude dependency in Apache Maven

Using Apache Maven, dependencies can be globally excluded in your project like so: <dependencies><dependency><groupId>log4j</groupId><artifactId>log4j</artifactId><version>1.2.17</version><scope>provided</scope></dependency></dependencies> Dependencies can be explicitly excluded for specific dependencies as well.

Azure Load Balancer uses a hash-based distribution algorithm.

By default, it uses a 5-tuple hash composed of source IP, source port, destination IP, destination port, and protocol type to map traffic to available servers. It provides stickiness only within a transport session. Packets in the same TCP or UDP session will be directed to the same instance behind the load-balanced endpoint. When the client closes and reopens the connection or starts a new session from the same source IP, the source port changes. This may cause the traffic to go to a different endpoint in a different datacenter.

TLS (formerly SSL) is a security protocol that can be added to HTTP to increase the security of your website

encryption: This protects the privacy of the communication between client and server.properly authenticating yourself: the client can trust that you are really you. The TLS handshake that is made at the beginning of the connection ensures the client that no one is trying to impersonate you;data integrity: this ensures that no one has tampered with the data in a request/response cycle; The TLS layer can be added to other protocols too, such as FTP (making it FTPS) or WebSockets (making ws://wss://).
