"Consul has multiple components, but as a whole, it is a tool for discovering and configuring services in your infrastructure. It provides several key features: Service Discovery: Clients of Consul can provide a service, such as api or mysql, and other clients can use Consul to discover providers of a given service. Using either DNS or HTTP, applications can easily find the services they depend upon. Health Checking: Consul clients can provide any number of health checks, either associated with a given service ("is the webserver returning 200 OK"), or with the local node ("is memory utilization below 90%"). This information can be used by an operator to monitor cluster health, and it is used by the service discovery components to route traffic away from unhealthy hosts. Key/Value Store: Applications can make use of Consul's hierarchical key/value store for any number of purposes including: dynamic configuration, feature flagging, coordination, leader election, etc. The simple HTTP API makes it easy to use. Multi Datacenter: Consul supports multiple datacenters out of the box. This means users of Consul do not have to worry about building additional layers of abstraction to grow to multiple regions. Consul is designed to be friendly to both the DevOps community and application developers, making it perfect for modern, elastic infrastructures."

"These are the major new features added since Slick 1.0.1: A code generator that reverse-engineers the database schema and generates all code required for working with Slick. New driver architecture to allow support for non-SQL, non-JDBC databases. Table definitions in the Lifted Embedding use a new syntax which is slightly more verbose but also more robust and logical, avoiding several pitfalls from earlier versions. Table definitions (and their * projections) are not restricted to flat tuples of columns anymore. They can use any type that would be valid as the return type of a Query. The old projection concatenation methods ~ and ~: are still supported but not imported by default. In addition to Scala tuples, Slick supports its own HList abstraction for records of arbitrary size. You can also add support for your own record types with only a few lines of code. All record types can be used everywhere (including table definitions and mapped projections) and they can be mixed and nested arbitrarily. Soft inserts are now the default, i.e. AutoInc columns are automatically skipped when inserting with +=, ++=, insert and insertAll. This means that you no longer need separate projections (without the primary key) for inserts. There are separate methods forceInsert and forceInsertAll in JdbcProfile for the old behavior. A new model for pre-compiled queries replaces the old QueryTemplate abstraction. Any query (both, actual collection-valued Query objects and scalar queries) or function from Column types to such a query can now be lifted into a Compiled wrapper. Lifted functions can be applied (without having to recompile the query), and you can use both monadic composition of Compiled values or just get the underlying query and use that for further composition. Pre-compiled queries can now be used for update and delete operations in addition to querying. threadLocalSession has been renamed to dynamicSession and the corresponding methods have distinct names (e.g. w

"Java 8 also brings many security improvements that are as important as the new language features. Of particular interest are the improvements to the TLS stack, implemented in the Java Secure Socket Extension (JSSE) component. Why? Because Java 7 and earlier do not give you enough control over TLS termination. As a result, it was simply not possible to terminate TLS at the Java level and achieve sufficient security. The deficiencies have been addressed in Java 8. Several other key improvements ensure that Java now provides a very good TLS stack. Many of the changes will take effect as you change the JRE, even with older applications."

"In Forrester's 40-criteria evaluation of application programming interface (API) management solutions, we identified the 11 most significant software providers in the category - 3scale, Apigee, Axway, CA Technologies, IBM, Informatica, Intel Services, MuleSoft, SOA Software, Tibco Software, and WSO2 - and researched, analyzed, and evaluated them. This report details our findings about how well each vendor's products fulfill our criteria and where they stand in relation to each other. This analysis, combined with three buying guides that highlight key make-or-break decision factors, will help AD&D professionals select the right partner for their API management needs."

"Bolt is a pure Go key/value store inspired by Howard Chu's and the LMDB project. The goal of the project is to provide a simple, fast, and reliable database for projects that don't require a full database server such as Postgres or MySQL."

"Terraform is a tool for building, changing, and versioning infrastructure safely and efficiently. Terraform can manage existing and popular service providers as well as custom in-house solutions. Configuration files describe to Terraform the components needed to run a single application or your entire datacenter. Terraform generates an execution plan describing what it will do to reach the desired state, and then executes it to build the described infrastructure. As the configuration changes, Terraform is able to determine what changed and create incremental execution plans which can be applied. The infrastructure Terraform can manage includes low-level components such as compute instances, storage, and networking, as well as high-level components such as DNS entries, SaaS features, etc. The key features of Terraform are: Infrastructure as Code: Infrastructure is described using a high-level configuration syntax. This allows a blueprint of your datacenter to be versioned and treated as you would any other code. Additionally, infrastructure can be shared and re-used. Execution Plans: Terraform has a "planning" step where it generates an execution plan. The execution plan shows what Terraform will do when you call apply. This lets you avoid any surprises when Terraform manipulates infrastructure. Resource Graph: Terraform builds a graph of all your resources, and parallelizes the creation and modification of any non-dependent resources. Because of this, Terraform builds infrastructure as efficiently as possible, and operators get insight into dependencies in their infrastructure. Change Automation: Complex changesets can be applied to your infrastructure with minimal human interaction. With the previously mentioned execution plan and resource graph, you know exactly what Terraform will change and in what order, avoiding many possible human errors."

"Let's Encrypt is a free, automated, and open certificate authority (CA), run for the public's benefit. Let's Encrypt is a service provided by the Internet Security Research Group (ISRG). The key principles behind Let's Encrypt are: Free: Anyone who owns a domain name can use Let's Encrypt to obtain a trusted certificate at zero cost. Automatic: Software running on a web server can interact with Let's Encrypt to painlessly obtain a certificate, securely configure it for use, and automatically take care of renewal. Secure: Let's Encrypt will serve as a platform for advancing TLS security best practices, both on the CA side and by helping site operators properly secure their servers. Transparent: All certificates issued or revoked will be publicly recorded and available for anyone to inspect. Open: The automatic issuance and renewal protocol will be published as an open standard that others can adopt. Cooperative: Much like the underlying Internet protocols themselves, Let's Encrypt is a joint effort to benefit the community, beyond the control of any one organization."

"The microservices architectural style simplifies implementing individual services. However, connecting, monitoring and securing hundreds or even thousands of microservices is not simple.A service mesh provides a transparent and language-independent way to flexibly and easily automate networking, security, and observation functions. In essence, it decouples development and operations for services.The Istio service mesh is split into 1) a data plane built from Envoy proxies that intercepts traffic and controls communication between services, and 2) a control plane that supports services at runtime by providing policy enforcement, telemetry collection, and certificate rotation.The near-term goal is to launch Istio to 1.0, when the key features will all be in beta (including support for Hybrid environments)The long-term vision is to make Istio ambient."
