SOAP (Simple Object Access Protocol)

Published

What is SOAP (Simple Object Access Protocol)?

SOAP (Simple Object Access Protocol) is a message protocol that enables the distributed elements of an application to communicate. SOAP can be carried over a variety of standard protocols, including the web-related Hypertext Transfer Protocol(HTTP).

SOAP was developed as an intermediate language for applications that have different programming languages, enabling these applications to communicate with each other over the internet. SOAP is flexible and independent, which enables developers to write SOAP application programming interfaces (APIs) in different languages while also adding features and functionality.

SOAP is a lightweight protocol used to create web APIs, usually with Extensible Markup Language (XML). It supports a wide range of communication protocols across the internet, HTTP, Simple Mail Transfer Protocol (SMTP) and Transmission Control Protocol. The SOAP approach defines how a SOAP message is processed, the features and modules included, the communication protocols supported and the construction of SOAP messages. SOAP uses the XML Information Set as a message format and relies on application layer protocols, like HTTP, for message transmission and negotiation.

SOAP building blocks and message structure example

Simple Object Access Protocol, as a specification, defines SOAP messages that are sent to web services and client applications. SOAP messages are XML documents that are comprised of the following three basic building blocks:

  1. The SOAP Envelope encapsulates all the data in a message and identifies the XML document as a SOAP message.
  2. The Header element contains additional information about the SOAP message. This information could be authentication credentials, for example, which are used by the calling application.
  3. The Body element includes the details of the actual message that need to be sent from the web service to the calling application. This data includes call and response information.

The fault message is an optional fourth building block. If a SOAP fault is generated, it is returned as an HTTP 500 error. Fault messages contain a fault code, string, actor and detail.

How does SOAP work?

SOAP requests are easy to generate and process responses. First, a request for a service is generated by a client using an XML document. Next, a SOAP client sends the XML document to a SOAP server. When the server receives the SOAP message, it sends the message as a service invocation to the requested server-side application. A response containing the requested parameters, return values and data for the client is returned first to the SOAP request handler and then to the requesting client. Both SOAP requests and responses are transported using Hypertext Transfer Protocol Secure (HTTPS) or a similar protocol like HTTP.

SOAP advantages and disadvantages

SOAP is an integral part of the service-oriented architecture (SOA) and the web services specifications.

Advantages of SOAP include the following:

  • Platform- and operating system-independent. SOAP can be carried over a variety of protocols, enabling communication between applications with different programming languages on both Windows and Linux.
  • Works on the HTTP protocol. Even though SOAP works with many different protocols, HTTP is the default protocol used by web applications.
  • Can be transmitted through different network and security devicesSOAP can be easily passed through firewalls, where other protocols might require a special accommodation.

Disadvantages, however, include the following:

  • No provision for passing data by reference. This can cause synchronization issues if multiple copies of the same object are passed simultaneously.
  • Speed. The data structure of SOAP is based on XML. XML is largely human-readable, which makes it fairly easy to understand a SOAP message. However, that also makes the messages relatively large compared to the Common Object Request Broker Architecture (CORBA) and its remote procedure call (RPC) protocol that will accommodate binary data. Because of this, CORBA and RPC are faster.
  • Not as flexible as other methodsAlthough SOAP is flexible, newer methods, such as RESTful architecture, use XML, JavaScript Object Notation, YAML or any parser needed, which makes them more flexible than SOAP.

SOAP APIs

SOAP is a protocol that is almost always used in the context of a web services or SOA framework. As such, its API is typically hidden by the higher-level interface for SOA. SOA API middleware tools are available for nearly all modern programming languages, and Microsoft offers a variety of .NET SOAP and SOA tools.

SOAP vs. REST

SOAP is designed to break traditional monolithic applications down into a multicomponent, distributed form without losing security and control. In contrast, REpresentational State Transfer (REST) is a model of distributed computing interaction based on the HTTP protocol and the way that web servers support clients. REST over HTTP is almost always the basis for modern microservices development and communications. RESTful APIs use HTTP requests to GET, PUT, POST and DELETE data.

REST over HTTP is simple, flexible, lightweight and offers little beyond a way of exchanging information. SOAP can ride on HTTP as well, but it connects the elements of a complex set of distributed computing tools — the web services and SOA framework — as well as application components, and this forms a part of a total service-oriented framework.

Future of Simple Object Access Protocol

SOAP was the first widely used protocol for connecting web services in a service-oriented architecture. Today, modern development of distributed applications is largely based on RESTful principles. SOAP is almost always confined to legacy platforms. One area where SOAP is still in use is in applications that handle online transactions, as it’s a style of API that is more rigid and protocol-driven.

4 Important Tips for Having a Vacation Abroad

Are you planning to go abroad but still don’t know what to prepare? People dream of going abroad, especially to countries like America and Europe. If this is your first time going abroad, you should check the following tips!

Prepare All Important Documents

The first thing you need to do is prepare important documents. For example, passports, ID cards, visas, and international driving licenses if you are going to drive abroad. Make sure you know whether the country you are going to visit is visa-free or not. For Southeast Asian countries, the Maldives and Turkey are visa-free, so you only have to have a passport. But a visa is still needed if you want to go to South Korea, Europe, or America. Make sure to scan your document and save it in the cloud like Google Drive or iCloud. Oh, yes, remember to check your vaccination status. Because every country needs your health information.

Make Itineraries

Itinerary is important for those who want to travel abroad. The reason is holidays abroad cost a lot of money, so when you can, take advantage of it with a well-planned schedule. Research in detail the tourist destinations you want to visit. For example, what is unique in it, ticket prices, transportation to get there, to the distance from the inn you’re staying. Remember to include places to eat that you want to try. Make sure the place to eat is according to your preferences, such as halal or free of certain food allergies.

Book Tickets in Advance

When you know how long you will be on vacation with the itinerary that has been prepared, it’s time to book plane tickets and lodging. Find cheap tickets by:

  1. Using promos and discounts on travel agent applications.
  2. Comparing which price is lower and what kind of facilities you will get.
  3. Choosing accommodation that fits your budget but is still comfortable.

Oh yes, also remember to check how the pandemic situation is in the country you are going to visit. Do you have to quarantine or not? Because it will affect your itinerary and accommodation. Due to the pandemic conditions that have not fully recovered, check whether there is still Indonesia quarantine after returning from vacation.

Exchange Money and Check Your ATM Cards

Exchange your currency into the destination country’s currency, for example, yen, euros, dollars, won, and others. But remember, don’t carry too much cash because it’s also prone to theft, besides being wasteful. For the rest, you can do cashless transactions. Check your bank’s ATM card to see if it has Visa, MasterCard, or Cirrus logos. This row of stamps indicates that your bank is working with banks abroad. Or you can also use a credit card to make your transaction easier.

Down 43%, Is This Tech Stock Worth Buying Right Now?

Down 43%, Is This Tech Stock Worth Buying Right Now?

Skyworks Solutions (NASDAQ: SWKS) announced its fiscal 2022 fourth-quarter results (for the three months ended September 30) on November 3, and the supplier Apple’s stock price has risen 11% since then.

Skyworks beat expectations and showed solid growth at a time when smartphone sales were declining, but forecasts show the chipmaker is about to hit a bump. With that said, let’s take a closer look at the latest results from the chipmaker. Let’s take a closer look at whether the stock can sustain new momentum after losing 43% of its value in 2022.

Skyworks solutions deliver reliable results for non-mobile businesses
Skyworks’ fourth-quarter revenue increased 7% year-over-year to a record $1.4 billion. The company also reported non-GAAP (adjusted) earnings of $3.02 per share, up 15% year-over-year. Skyworks easily justified analyst estimates of $2.91 per share. For the year, the company’s revenue increased 7% to $5.5 billion and earnings rose similarly to $11.24 per share.

The strong growth of chipmakers in the fourth quarter was the result of successful diversification into new markets such as Internet of Things (IoT) and automotive, as well as relationships with major smartphone original equipment manufacturers (OEMs). Yes, it helped make up for it. Weakness in the smartphone market. space. However, it was the non-mobile business that put a lot of effort into Skyworks last quarter.
As CFO Chris Sennesael noted in the report, the company generated $500 million in revenue from broad market segments (counting chip sales for non-mobile applications like IoT), up 30% from the previous year. Last earnings conference call. Broad market companies contributed 36% of Skyworks’ revenue last quarter, up from 29% in the same period last year.

It’s also worth noting that Skyworks earned $2 billion in revenue from this segment for the entire fiscal year. That’s almost 43% more than the $1.4 billion in revenue last fiscal year. The good news is that the company’s business in a wide range of markets can maintain its momentum. This is because, as Skyworks showed in its earnings report, it is attracting new customers in high-growth niches like IoT.

“In IoT, we continue to win new customers and expand our content. We have partnered with Vodafone to launch the UK’s first WiFi 6E platform. We have launched a solution for Fi 6 hotspots.”

Skyworks also enables the deployment of O-RAN (Open Radio Access Network) and delivers record quarterly results in the high-growth automotive business niche. For example, the O-RAN market is expected to grow at an annual rate of 42% until 2030. Meanwhile, according to Mordor Intelligence, the demand for connected cars will grow by 19% per year until 2027.

These catalysts explain why Skyworks expects its broad commercial segment of the market “to be a major driver in FY23 and beyond.”

The mobile business was not in its best last quarter
Skyworks’ mobile business generated approximately $907 million in revenue last quarter (this is total revenue minus $500 million from the broader market business). By comparison, 71% of Skyworks’ $1.31 billion in revenue last year came from its mobile business, worth nearly $931 million.

Thus, the company’s mobile business, which generates most of its revenue, declined year-over-year in the most recent quarter. This is not surprising given that smartphone sales have been declining for the past five quarters. Skyworks considers Apple its biggest client, with the smartphone giant generating 58% of its revenue last year.

Last quarter, Apple shipped 48.5 million smartphones, 6.4% more than last year. However, the overall smartphone market was down 9% year-over-year. And now things could get even worse for Skyworks.

All of this explains why Skyworks management is targeting a sharp drop in sales and profits. The chipmaker expects revenue of $1.3 billion to $1.35 billion and adjusted earnings of $2.59 per share in the first quarter of fiscal 2023. These numbers show double-digit declines in both revenue and earnings compared to the last year.
